The Palm Springs ShortFest has announced its lineup for the 2011 edition running June 21-27. Event will showcase 331 films, including 64 world premieres and 25 U.S. premieres.

Fest, now in its 17th year, will include “Bad Dads,” with Michael Cera; “Sexting,” with Julia Stiles; “The Second Bakery Attack,” with Kirsten Dunst and Brian Geraghty; and “Steve,” with Keira Knightley and Colin Firth.

Helmers of this year’s short films include Peter Cattaneo, Jay Duplass, Terry George, David Hayter and Heather Hemmens. Olivia Wilde and Maria Bello serve as exec producers on David Darg’s Haitian-shot docu “Sun City Picture House.”

Fest will hand out $118,000 in prizes in 18 categories, with director Allison Anders, producer Effie T. Brown and producer-writer Kirsten Smith on the jury. First-place winners in four categories are eligible for submission to the Oscars. In the past 16 years, 80 films that screened at the fest have gone on to be Oscar nommed.

Event will also hold panels along with its inaugural ShortFest Online Film Festival, in which 10 films will rep the fest on the Web.

“It’s a watershed year for ShortFest,” remarked Festival Director Darryl Macdonald. “It encompasses our first foray into the world of online short film streaming, an expanded lineup of international participants and new sponsors.”
