The Nantucket Film Festival will in June honor Oscar-nominated writer-director Noah Baumbach and Oscar-winning documentary filmmaker Morgan Neville and switch up its annual comedy roundtable to improv with actors-comedians Thomas Middleditch and Ben Schwartz.

The 23rd annual festival, which runs June 20-25, also will recognize Andrew Heckler as a New Voice in Screenwriting and host a June 21 live taping of National Public Radio’s “Ask Me Another” game show — which mixes trivia with comedy and music — with festival regular Ophira Eisenberg. Special guests for the show will be announced later.

The Screenwriters Tribute to Baumbach, director of “The Squid and the Whale” and “The Meyerowitz Stories (New and Selected),” will take place June 23. Neville, whose films include “20 Feet From Stardom,” “Best of Enemies” and “Won’t You Be My Neighbor,” about the legacy of longtime Nantucket resident Fred Rogers of TV’s “Mister Rogers,” will be honored separately with an award for Special Achievement in Documentary Storytelling. Heckler, a longtime actor, won the audience award at the Sundance Film Festival for “Burden,” the true story of the redemption of a Klansman.

Actor/director/writer Ben Stiller will again present the All-Star Comedy Roundtable, although as “The Improv Takeover,” with Middleditch, best known for TV’s “Silicon Valley,” and Schwartz, of “Parks and Recreation.” They will kick off a soldout national tour of spontaneous storytelling and improvisational comedy with a special festival version featuring Stiller on June 22.

Festival passes are on sale now, and ticket packages will go on sale at noon April 24 on the festival’s website at
