Celebrities did not keep quiet during the 2016 presidential race.
And some simply said they didn't like then-Republican presidential candidate Donald Trump, who of course went on to win the race in November.
Scroll down to see which celebrities denounced The Donald during his run for the presidency.
Robert De Niro
Actor and New Yorker Robert De Niro has made his opinions on Donald Trump pretty clear. He spoke publicly about his stance on Trump at the 22nd Sarajevo Film Festival on Saturday, Aug. 13, 2016, calling the presidential candidate "totally nuts."
"It's crazy that people like Donald Trump . . . he shouldn't even be where he is, so God help us," de Niro said.
He has also spoken in favor of Hillary Clinton. In April 2015 he told The Daily Beast that Hillary Clinton has "earned the right to be president."
Actress Lena Dunham has campaigned in support of Hillary Clinton, and speaking at the Democratic National Convention on July 26, 2016, she called out Trump for past remarks about women.
"Donald and his party think I should be punished for exercising my constitutional rights, and his rhetoric about women takes us back to a time when we were meant to be beautiful and silent," she said.
Mark Ruffalo, Shonda Rhimes, Bryan Cranston, more
Actor Mark Ruffalo, producer Shonda Rhimes, actor Bryan Cranston and many more artists signed a petition titled "Artists united against hate," that says they are committed "to defeat the presumptive Republican nominee for president, Donald Trump."
"Trump wants to take our country back to a time when fear excused violence, when greed fueled discrimination, and when the state wrote prejudice against marginalized communities into law,' the petition says.
Actress America Ferrera wrote an open letter to Donald Trump, published on Huffington Post, thanking him for his "hateful rhetoric" about Mexican immigrants because it will energize Latino voters to vote for other candidates.
"Remarks like yours will serve brilliantly to energize Latino voters and increase turnout on election day against you and any other candidate who runs on a platform of hateful rhetoric," she wrote.
"You, Mr. Trump, are living in an outdated fantasy of a bigoted America," she continued.
In her DNC speech on July 26, 2016, she said, "Donald's not making America great again, he's making America hate again. The vast majority of us cannot afford to see his vision of America come to be."
Renowned scientist Stephen Hawking said in an interview on May 31, 2016, that he can't understand Trump's political rise. "He is a demagogue, who seems to appeal to the lowest common denominator," he told "Good Morning Britain."
John Oliver used nearly the entire season finale of his HBO show on Nov. 13, 2016, to criticize President-elect Donald Trump.
Author Stephen King joined over 400 writers in signing a petition that speaks out against Trump. The petition, released on May 24, lists a number of reasons why the group of writers "oppose, unequivocally, the candidacy of Donald J. Trump."
"The rise of a political candidate who deliberately appeals to the basest and most violent elements in society, who encourages aggression among his followers, shouts down opponents, intimidates dissenters, and denigrates women and minorities, demands, from each of us, an immediate and forceful response," the petition reads.
The petition was written by writers Andrew Altschul and Mark Slouka. Cheryl Strayed and Amy Tan are among the others who signed. The group also started a Twitter account, @WritersOnTrump, and the hashtag #WritersOnTrump.
In an interview with "The Young Turks" in January, actress Susan Sarandon compared Trump to a "drunk uncle at a wedding."
She said she "can't even address him seriously," but what concerns her is that "he's made hatred and racism normal." She said she "can't believe for a second that America would actually make Donald Trump the president," and that many Republicans must be embarrassed by him.
Singer-songwriter John Legend called Trump "racist" on Twitter after Trump's son, Donald Trump Jr. tweeted about the clashes between Trump supporters and protesters in Chicago.
"Ha 5 students when asked why they were protesting couldn't even answer. The participation medal/micro aggression generation is pretty sad!," Trump Jr. tweeted.
".@DonaldJTrumpJr I think they were protesting your racist father. This isn't complicated," Legend wrote.
After the exchange received media attention, Legend tweeted, "This is not controversial. This is not news. The sky is blue."
Appearing on the Australian "Today" show on March 14, actor Jack Black said he would choose anyone for president over Trump, even hip-hop artist Kanye West.
"Listen, I'll take Kanye over Trump, anyone but Trump," he said. When asked what he thought of the prospects of Trump becoming president, Black said, "It's a scary proposition but I don't think that's really in the cards."
"At the end of the day, you gotta believe that people are gonna vote for someone who's more levelheaded, and more responsible, maybe a little more intelligent," he said. "This guy's just a hot head and he's a billionaire, and how can you trust that he's not just going to be looking out for No. 1, as he always has?"
Comedian Sarah Silverman has made her views on Trump very clear on Twitter, often replacing his name with "Drumpf," the original name of Trump's ancestors.
"DRUMPF is NEGGING us and we've fallen for it - we're obsessed w this candidate we had no intention of ever acknowledging #TheGame," she tweeted on March 11, 2016.
Silverman, who has endorsed Bernie Sanders, also mocked Trump on "Conan" by dressing as Adolf Hitler and talking about the comparisons people have made between the two.
"Don't get me wrong Conan, I agree with a lot he says," Silverman as Hitler said. "A lot. Like 90 percent of what he says, I'm like, 'This guy gets it.'"
But, Silverman added, "All these comparisons to Trump, it's like, it bums me out."
"Sometimes I watch him and I'm like, 'Is that how people see me?'"
Samuel L. Jackson
Actor Samuel L. Jackson and Trump had a short Twitter feud in January over whether or not they had played golf together.
Jackson said in an interview with Rhapsody Magazine that Trump had signed him up as a member of one of his golf clubs without his knowledge, and then sent him a bill. He also said he "would never say" he and Trump were "buddies," but they did play golf together. He added that Trump is an "interesting character," "more P.T. Barnum than politician" and that he is a better golfer than Trump because he doesn't cheat.
Trump quickly responded on Twitter, denying that he even knew Jackson and said, "to best of my knowledge haven't played golf w/him."
Jackson then posted a picture of the bill from Trump's golf club on Instagram, with the caption, "A bill from the guy that doesn't know me & never golfed with me! I'm gonna Block his a-- too!"
Comedian Chelsea Handler tweeted a picture of herself almost naked with "Trump is a butt hole" written on her body.
"A germane tweet," she wrote on Twitter. "I mean this with the utmost disrespect."
She also tweeted a picture of herself holding a Trump piñata and "trying to find a good tree" to hang it up in Aguascalientes, Mexico.
Comedian John Oliver dedicated a 20-minute segment of "Last Week Tonight" to denouncing Trump.
Oliver pointed out many of the discrepancies about Trump, refuting the reasons why people support him, including that he tells it like it is, his financial independence, his toughness and that he is a successful businessman.
"I get that the character of Donald Trump is entertaining, that he says things that people want to hear, and I know his very name is powerful," he said. "The very name Trump is the cornerstone of his brand. If only there was a way to uncouple that magical word from the man he is."
Oliver then revealed that one of Trump's ancestors had changed the family name from "Drumpf."
"Stop and take a moment to imagine how you would feel if you just met a guy named Donald Drumpf, a litigious serial liar with a string of broken business ventures and the support of a former Klan leader he can't decide whether or not to condemn," Oliver said.
He also created the hashtag #MakeDonaldDrumpfAgain and asked viewers to download a "Drumpfinator" Chrome extension that would replace the word Trump with Drumpf anywhere online.
She has spoken out a number of times on Twitter about Trump since then, calling him "a pathological liar," "a racist," "a fascist" and "disgusting & despicable." She has also compared Trump to Adolf Hitler, questioned his ability to "face ISIS" when he threatened to not participate in a debate and said he would start a "race war" if he is elected
In an interview with ABC News (Australia) in January, actor Ben Stiller said he was surprised Trump's campaign has "gone on this long, with the rhetoric that he puts out there."
He said Trump is "like the villain in a Naked Gun movie or something. I can't take him seriously, but some people are taking him seriously, which is the crazy thing."
"I don't see it going all the way," he added.
"Harry Potter" author J.K. Rowling told her fans on Twitter that she thinks Trump is worse than Voldemort.
"How horrible," she wrote, sharing an article about people comparing the presidential candidate to the villain. "Voldemort was nowhere near as bad."
The "Humans of New York" founder Brandon Stanton published an open letter to Trump on Facebook on March 14. In the letter, he called out Trump for sharing racist images and remarks on social media, encouraging violence at his rallies and claiming that "Islam hates us."
"Over the last two years I have conducted extensive interviews with hundreds of Muslims, chosen at random, on the streets of Iran, Iraq, and Pakistan," Stanton wrote. "I've also interviewed hundreds of Syrian and Iraqi refugees across seven different countries. And I can confirm-- the hateful one is you."
"You are not a 'unifier.' You are not 'presidential.' You are not a 'victim' of the very anger that you've joyfully inflamed for months," he wrote. "You are a man who has encouraged prejudice and violence in the pursuit of personal power."
Playwright and activist Eve Ensler wrote a column for The Guardian calling for people to unify against Trump.
"Donald Trump is not a leader or a presidential candidate," she wrote. "He is an outcome, a viral manifestation of a serious malignant illness ... He is the outcome of the rich being able to buy anything, including our democracy ... He is the outcome of an insanely violent culture, increasingly unkind with more bullying, that normalizes cruelty, industrializes punishment and declares endless war on its own citizens."
"He is not us," she said. "He is not all of us. He is not the best of us. He is not inevitable. Let us take Trump at his word. Let him be our Unifier."
Kerry Washington is one among a number of celebrities who have joined the "Stop Hate, Dump Trump" campaign.
"Join me + #EveEnsler, @harrybelafonte, @sandylocks, @MMFlint and @thandienewton to say enough #StopHateDumpTrump," she tweeted in January.
Actor George Clooney called Trump "a xenophobic fascist" in an interview with The Guardian, published on March 3.
Calling Trump's proposition to ban Muslims from entering the United States "a massively stupid idea," Clooney said, "in election season, things go crazy, and the loudest voices are the furthest and most extreme."
"He's just an opportunist," Clooney said of Trump. "Now he's a fascist; a xenophobic fascist."
"You can count on Americans to do the right thing after they've exhausted all the other possibilities," he added.
In an interview with Entertainment Weekly in October, actress Jennifer Lawrence said, "If Donald Trump is president of the United States, it will be the end of the world."
Her "Hunger Games" co-stars, Liam Hemsworth and Josh Hutcherson didn't argue.
"It's a publicity stunt," Hutcherson said of Trump's presidential campaign at the time. "It can't be real."
Actor Johnny Depp, who did an impression of Trump in a parody video by "Funny or Die," spoke about the presidential candidate at an appearance at Arizona State University on March 12, calling him "a brat."
"I approached Donald Trump as what you kind of see in him when you really watch him," he said. "There's a pretense. There's something created about him in the sense of bullydom. But what he is, I believe, is a brat."
Singer Miley Cyrus called Trump a "nightmare" on Instagram on Super Tuesday, when Trump won a number of states.
She also said she would move to another country if Trump is elected, using the hashtag #aintapartyindausaanymo (aint a party in da usa anymo)
In an email to his fans on March 5, comedian Louis C.K. wrote a lengthy plea for them to not vote for Donald Trump.
"Please stop it with voting for Trump," he wrote. "It was funny for a little while. But the guy is Hitler."
"If you are a true conservative," the email reads. "Don't vote for Trump. He is not one of you. He is one of him."
"He's an insane bigot," he wrote. "He is dangerous."
Producer Russell Simmons wrote an open letter to Trump in December 2015, titled "To My Old Friend Donald Trump, Stop The Bulls---"
Simmons wrote that Trump has been a friend and supporter of his, but "what's at stake is bigger than us."
Simmons reminded Trump that he is the Chairman of The Foundation for Ethnic Understanding, "whose sole mission is to fight bigotry of all kinds."
"My friends, both Muslims and Jews, are saying there are so many comparisons between your rap and Hitler's, and I cannot disagree with them, Donald," he wrote.
Simmons also tweeted in March, "The campaign @realDonaldTrump is running is dangerous, racist and violent. This is not the man I've known for decades. He must be stopped."
Singer Shakira also reacted to Donald Trump's comments about Mexican immigrants, tweeting, "This is a hateful and racist speech that attempts to divide a country that for years has promoted diversity and democracy!"
"No one living in this century should stand behind so much ignorance," she wrote on Twitter.
In an interview with the Evening Standard, published in March, actor Richard Gere said Trump is "a guy who's obviously Mussolini."
"He's finding villains everywhere and then telling people he'll get rid of them," Gere said. "We'll get rid of the Jews, the blacks. Anyone that we perceive as a problem, we'll get rid of. This is how it starts. Intelligent people aren't seeing this -- don't make the mistake of thinking it's just idiots who are backing Trump -- this kind of thinking is a slippery slope."
Actress and comedian Rosie O'Donnell and Trump have had a history of publicly denouncing each other, and it has continued throughout Trump's campaign.
In an interview with EW, O'Donnell said Trump's campaign was "a nightmare."
She also tweeted, "try explaining that 2 ur kids," after Trump responded to questions about calling women "fat pigs, dogs, slobs, disgusting animals," with "Only Rosie O'Donnell" in a Fox GOP debate in August.
Singer Bette Midler drew attention when she tweeted a meme of Trump with a quote from the novel "Catch 22."
"It was miraculous," the quote reads. "It was almost no trick at all, he saw, to turn vice into virtue and slander into truth, impotence into abstinence, arrogance into humility, plunder into philanthropy, thievery into honor, blasphemy into wisdom, brutality into patriotism, and sadism into justice. Anybody could do it; it required no brains at all. It merely required no character."
The image of Trump with the quote originally appeared in the book "Slaughterhouse 90210."
Midler has tweeted a number of times about the presidential candidate, and even criticized his supporters.
".@RealDonaldTrump gets close to the nomination. Now I see why we needed warnings on plastic bags telling us not to put them over our heads," she said on Twitter.
Bill de Blasio
Mayor Bill de Blasio, who has campaigned for Hillary Clinton, is another public figure to call the GOP front-runner "a racist."
Speaking on CNN, he defended his statement, saying "It's a clear pattern of division and using race as a wedge and using it as a strategic tool. That's racism."
"We've seen these kind of historical parallels before," de Blasio added. "The xenophobia, the racism, the call to violence. This is when democracies start to break down a little bit, when someone like this emerges and they're not stopped and they're not countered. So this is the moment when people have to stand up and say, 'Donald Trump doesn't represent our democracy.'"
