DC Entertainment has released the first footage of its upcoming movie featuring its longstanding mythological superhero Wonder Woman.

As part of The CW’s “Dawn of the Justice League” special on Tuesday night, DC Comics Chief Creative Officer Geoff Johns, 42, introduced footage of star Gal Gadot as Amazonian princess Diana as she leads horsemen, including fellow star Chris Pine, through misty woods on the fictional Greek island of Themyscira. (That’s the name of the real-life ancient Greek town from which the mythological Amazons were said to have hailed.)

“These Amazons were once created to protect man’s world, but they since abandoned it,” Johns tells filmmaker and comics fan Kevin Smith, 45, who is not involved with the movie but has written for DC. “And Diana is asking constantly, ‘Why don’t we go do what we were created to do and protect man?’ And they say, ‘Because they’re not worth it.’ And this takes her on a journey into our world.”

“We’re going to see her coming of age, the entire history, what’s her mission,” says Israeli actress Gadot, 30, in an interview snippet.

The footage includes Diana in human garb, trying on glasses, and ends with her on Themyscira galloping into a fray, sword in hand.

“Wonder Woman,” directed by Patty Jenkins (“Monster,” for which star Charlize Theron won an Academy Award), is set for release on June 23, 2017. Gadot will first appear as Wonder Woman in this March’s superhero feature “Batman v Superman: Dawn of Justice.”
