The Nantucket Film Festival has announced that Jim Carrey and Chris Rock will join the All-Star Comedy Roundtable, presented by Ben Stiller. The event takes place Friday at 3 p.m. and benefits the Nantucket Film Institute’s programs such as the Teen View Writing Labs and Script Analysis Service.

On Saturday at 1 p.m., the fest presents a staged reading of a film project in the works — this year’s reading is Jim Taylor and Alexander Payne’s “The Lost Cause,” with cast members including Steve Zahn, Mike Birbiglia, Anne Meara and Tim Ransom. The Nantucket Film Fest takes place Wednesday through Sunday.
