The 114 feature films of the 2017 Sundance Film Festival just grew by two — or four, depending on how you look at it. There’ll also be one more hot ticket with Quentin Tarantino appearing live at the Utah shindig.

Running from January 19-29 in Park City, Salt Lake City and at the Sundance Mountain Resort, the Robert Redford-founded fest today added the world premieres of American documentaries Bending the Arc and the Grateful Dead-spotlighting Long Strange Trip to its lineup.

Additionally with those new pics, Sundance has dusted off two old favorites, with Quentin Tarantino’s Reservoir Dogs back for its 25th anniversary and the 31st anniversary of Donna Deitch’s Desert Hearts. After the screening of the new 35mm print of the former, Tarantino and producer Lawrence Bender will participate in a Q&A with fans and fellow filmmakers. Both Reservoir Dogs and Desert Hearts are drawn from the Sundance Institute Collection at UCLA, which was established in 1997.

It’s not quite our 25th anniversary, but Deadline co-Editor-in-Chief, Film, Mike Fleming Jr. and myself again will lead our Sundance coverage next month with breaking news on the deals, the films, the panels and what’s going down on the streets of Park City.

Here are the films announced today:

DOCUMENTARY PREMIERES

Bending the Arc / U.S.A. (Directors: Kief Davidson, Pedro Kos, Screenwriter: Cori Shepherd Stern) — This powerful epic is about the extraordinary doctors and activists—including Paul Farmer, Jim Yong Kim, and Ophelia Dahl—whose work 30 years ago to save lives in a rural Haitian village grew into a global battle in the halls of power for the right to health for all. World Premiere

Long Strange Trip / U.S.A. (Director: Amir Bar-Lev) — The tale of The Grateful Dead is inspiring, complicated, and downright messy. A tribe of contrarians, they made art out of open-ended chaos and inadvertently achieved success on their own terms. Never-before-seen footage and interviews offer this unprecedented and unvarnished look at the life of the Dead. World Premiere

FROM THE COLLECTION

Desert Hearts / U.S.A. (Director: Donna Deitch, Screenwriter: Natalie Cooper) — Nevada, 1959: Vivian Bell arrives to get a divorce and finds herself increasingly drawn to Cay Rivvers, a self-assured lesbian. The emotions released by their developing intimacy combined with Vivian’s insecurities are played out against a backdrop of rocky landscapes and country and western songs. The Festival will screen a new digitally restored version by the Criterion Collection and UCLA Film & Television Archive in conjunction with Sundance Institute and Outfest UCLA Legacy Project. Cast: Andra Akers, Dean Butler, Patricia Charbonneau, Audra Lindley, Helen Shaver, Glen Welles.

Reservoir Dogs / U.S.A. (Director and screenwriter: Quentin Tarantino) — They were perfect strangers, assembled to pull off the perfect crime. Then their simple robbery explodes into a bloody ambush and the ruthless killers realize one of them is a police informant. But which one? Miramax provided a brand-new 35mm print for this special 25th anniversary screening, which will be followed by an extended Q&A with Tarantino and producer Lawrence Bender. Cast: Harvey Keitel, Tim Roth, Chris Penn, Steve Buscemi, Lawrence Tierney, Michael Madsen.
