The entries includes director Jake Scott's New Orleans drama "Welcome to the Rileys," which co-stars Gandolfini and "Twilight" star Kristen Stewart. Gandolfini's "The Sopranos" co-star Falco is among the cast of Eric Mendelsohn's suburban drama "3 Backyards," while Natalie Portman stars alongside Joseph Gordon-Levitt and Rainn Wilson in Spencer Susser's family tale "Hesher."
The films are among 16 screening in the U.S. drama contest and were selected from more than 1,000 movies submitted to Robert Redford's independent-film showcase, which runs Jan. 21-31 in Park City, Utah.
Other titles announced Wednesday include Rob Epstein and Jeffrey Friedman's "Howl," an Allen Ginsberg tale starring James Franco, Mary-Louise Parker, Jon Hamm and David Strathairn; Tanya Hamilton's racial drama "Night Catches Us," with Anthony Mackie and Kerry Washington; and Kevin Tyler Asch's Ecstasy-smuggling crime story "Holy Rollers," featuring Jesse Eisenberg.
The competition presents stars of past top prize winners at Sundance. Among them are Derek Cianfrance's marital drama "Blue Valentine," with Michelle Williams and Ryan Gosling, who starred in the festival's 2001 grand jury award winner "The Believer."
Melissa Leo - who starred in last year's grand jury prize winner, "Frozen River," which earned her an Academy Award nomination - appears in two competition films this time: Stewart and Gandolfini's "Welcome to the Rileys" and Ryan Piers Williams' war-homecoming drama "The Dry Land." The latter also features "Ugly Betty" star America Ferrera, whose career break came with "Real Women Have Curves," which won the 2002 audience award as favorite U.S. drama among Sundance movie-goers.
Mark Ruffalo makes his directing debut with the faith-healing story "Sympathy for Delicious," reuniting him on-screen with Laura Linney, his co-star in "You Can Count on Me," which shared the festival's 2000 grand jury prize. "Sympathy for Delicious" also stars Orlando Bloom and Juliette Lewis.
The 16 films in Sundance's U.S. documentary competition include "Casino Jack & the United States of Money," a study of corruption surrounding former lobbyist Jack Abramoff that was directed by Alex Gibney, whose "Taxi to the Dark Side" won the 2007 documentary Oscar.
Davis Guggenheim - whose Al Gore global-warming story "An Inconvenient Truth" premiered at Sundance in 2006 and won the documentary Oscar for that year - returns to the festival with the competition documentary "Waiting for Superman," which scrutinizes the American public-education system.
Also in the documentary competition are Jessica Hernandez's "Bhutto," a portrait of slain Pakistani leader Benazir Bhutto; Robin Hessman's "My Perestroika," which traces the lives of five Moscow residents after the Soviet Union's collapse; and Sebastian Junger and Tim Hetherington's "Restrepo," which examines the war in Afghanistan.
Sundance organizers also announced the lineup of 16 films each in the festival's world-cinema narrative and documentary categories.
Other titles among the festival's 113 feature-length films, including star-studded premieres screening out of competition, will be announced Thursday.
Sundance is dispensing with its opening-night tradition of premiering a film that is not competing for a prize. Instead, it will start with screenings of one dramatic competition film and one entry in the documentary competition. Those opening films will be announced later.
"We decided to launch into the competition rather than trying to find a film that encapsulates the whole eclectic group that follows," said John Cooper, a longtime Sundance programmer who is overseeing the show for the first time after being promoted to festival director in March.
