Slamdance, launched 18 years ago as an alternative to Sundance, has unveiled its competition lineup with 10 narrative films and eight documentaries — including 13 world premieres.

The lineup, announced Wednesday, was culled from nearly 5,000 submissions. Slamdance will take place Jan. 20-26 in Park City, Utah, at the Treasure Mountain Inn.

Special screenings and shorts in competition will be announced next week. Competition slots, totaling about 100, are reserved for first time feature directors working with budgets under $1 million.

Two titles already generating buzz are “Bindlestiffs” in the feature lineup and “We Are Legion: The Story of Hacktivists” in documentaries. “Bindlestiffs,” directed by Andrew Edison, stars Andrew Edison, Luke Loftin and John Karna as smart-mouthed high school virgins, who are suspended from school on a graffiti charge and flee to the inner city to live out the plot of “The Catcher in the Rye.”

“We Are Legion,” directed and written by Brian Knappenberger, is a look inside the world of Anonymous, the radical “hacktivist” collective that’s redefined civil disobedience for the digital age.

Other feature entries — “Comforting Skin,” directed by Derek Franson, starring Jane Sowerby, Tygh Runyan, Victoria Bidewell; “Doppelganger Paul (or A Film About How Much I Hate Myself),” directed by Dylan Akio Smith and Kris Elgstrand, starring Brad Dryborough and Tygh Runyan; “Faith, Love and Whiskey,” directed by Kristina Nikolova, starring Ana Stojanovska, Valeri Yordanov, John Keabler, Lidia Indjova, Yavor Baharov; “Heavy Girls,” directed by Axel Ranisch, starring Heiko Pinkowski, Peter Trabner, Ruth Bickelhaupt; “OK, Good,” directed by Daniel Martinico, starring Hugo Armstrong; “Roller Town,” directed by Andrew Bush, starring Kayla Lorette, Mark Little and Scott Vrooman: “The Sound of Small Things,” directed by Peter McLarnan, starring Cara Krippner and Sam Hoolihan; “Sundowning,” directed by Frank Rinaldi, starring Shannon Fitzpatrick and Susan Chau; and “Welcome to Pine Hill,” directed by Keith Miller, starring Shannon Harper, Mary Meyers, David Williams
