Hamptons International Film Festival will honor Dick Cavett at its 25th anniversary

Margot Robbie, Patrick Stewart and Rob Reiner will be among the celebrity guests at the 25th anniversary of the Hamptons International Film Festival, which also features an exhibit of 25 years of festival poster art, a first-ever Dick Cavett Artistic Champion Award — to be given to Cavett — and a lifetime achievement award that will go to the screen legend Julie Andrews. The festival’s opening-night screening of the documentary “Itzhak” will be attended by its subject, the violinist Itzhak Perlman.

It’s the culmination of a yearlong celebration that has included screenings of one film from each of the festival’s past years (Its very first big “get” was Jane Campion’s Oscar-winning “The Piano”) and a pre-festival party in June attended by, among others, co-chairman Alec Baldwin, board member Bob Balaban and the director Joel Schumacher (1990’s “Flatliners”).

“It’s important to us to communicate that we’ve been doing this for 25 years,” says festival executive director Anne Chaisson, “and we will continue to do so for the future.”

Here are several highlights from this year’s festival. All times are after noon except where noted. Keep in mind that many films will have repeat screenings.
