Itzhak Perlman attended the Hamptons International Film Festival Thursday night to attend a screening of “Itzhak,” a documentary about his life and career.

“I’ve seen it — not totally finished,” Perlman said of the film as he entered the theater in his motorized wheelchair. “So I’m going to get a little surprise. I didn’t want to see everything. I just wanted to have a good time.”

The 72-year-old musician, whose legs were paralyzed by polio at a young age but who became one of the world’s greatest violinists — and an East End resident for nearly 30 years — helped kick off the 25th year of the Hamptons film festival, which runs through Monday, Oct. 9. Also scheduled for opening night was the presentation of the first-ever Dick Cavett Artistic Champion award to its namesake, the 80-year-old former talk-show host, during an invite-only party in East Hampton. Perlman and Cavett were the first in what promises to be an influx of well-known media and entertainment figures over the festival’s coming days.

On Saturday, the festival’s “10 Actors to Watch” panel will include Kumail Nanjiani of “The Big Sick” and Ali Fazal of “Victoria and Abdul.” Also on the panel will be Daniel Kaluuya of “Get Out,” who on Sunday will return to break down a scene from his hit horror film with producer Jason Blum and co-star Allison Williams.

Patrick Stewart will sit for a live interview Saturday afternoon at East Hampton Middle School, while across town at Guild Hall, Julie Andrews will accept a lifetime achievement award. It will be presented after a special screening of “Victor Victoria,” Andrews’ 1982 musical with director-husband Blake Edwards, who died in 2010.

Annette Bening and Rob Reiner will both hold Q&A sessions Sunday, followed by Margot Robbie’s appearance Monday at the closing-night film, “I, Tonya,” in which she plays disgraced figure skater Tonya Harding.
