Julie Andrews, Patrick Stewart and Kumail Nanjiani attended the Hamptons International Film Festival on Saturday, part of a celebrity-packed weekend that also included an appearance by festival co-chair Alec Baldwin.

Others who showed up Saturday included Danielle Macdonald of the rap-themed drama "Patti Cake$," Daniel Kaluuya of the hit horror film "Get Out" and Timothee Chalamet of the gay romance "Call Me By Your Name."

Those actors and others kicked off the morning as part of Variety's annual "10 Actors to Watch" panel, which included Nanjiani, the Pakistani-American star of "The Big Sick." During an informal conversation at East Hampton's Rowdy Hall restaurant, the mostly young actors (Nanjiani, 39, was an elder statesman) talked about their fears of failure and recent triumphs.

Macdonald, who never expected to receive critical acclaim playing a New Jersey rapper, pointed out, "I can't rap, and also I'm Australian." Grace Van Patten, a star of Noah Baumbach's "The Meyerowitz Stories (New and Selected)" said that despite holding her own with co-stars Dustin Hoffman and Adam Sandler, "I still wake up in my bed thinking I'm in a scene." Nanjiani recalled trying to pitch a terrible idea to his eventual producer, Judd Apatow: "One of my ideas was about a ghost witch, about a woman who dies and then comes back as a ghost - but she was a witch. He was like, 'Do you have any other ideas?' "
