As the entertainment industry grapples with the devastating impact of the California wildfires, many are heading to cleaner mountain air. The annual Sundance Film Festival kicks off Thursday in Park City, Utah.

The 41st edition of Robert Redford’s brainchild will, as always, be a year of discovery and discussion. There are timely films:

— “Free Leonard Peltier,” which will premiere just days after former President Joe Biden commuted the sentence of the Indigenous activist nearly half a century after he was imprisoned for the 1975 killings of two FBI agents.

— Oscar-winner Mstyslav Chernov’s“2000 Meters to Andriivka,” a joint production between The Associated Press and Frontline about an attempt to liberate an occupied territory in Ukraine

— Several films about trans rights including “Heightened Scrutiny,” about civil rights lawyer Chase Strangio. It's a topic even more pressing after President Donald Trump signed executive orders Monday rolling back protections for transgender people.

There are even some controversies brewing: “The Stringer,” from documentary filmmaker Bao Nguyen, calls into question who took the Pulitzer Prize-winning “Napalm Girl” photograph. Retired AP photographer Nick Ut and the AP, which conducted a six-month investigation into the allegation, are contesting it and Ut's lawyers have asked for it to be pulled from the program.

“The film is an investigation,” said Eugene Hernandez, the director of the festival, who is moving forward with plans to screen it. “I think it will be a really important conversation that will come out over the next few days after the film is seen by more people.”

Don’t worry, it’s not all heavy. There’s drama of course, even a film about starting over after a fire (“Rebuilding,” with Josh O’Connor), horror, satire, literary adaptations, comedy, documentaries about famous faces, and some that simply defy categorization.

“There’s some really funny stuff in the program,” Hernandez said. One of those Hernandez cited is “Bubble & Squeak,” about a married couple accused of smuggling cabbages into a nation where they’re banned.

For first time filmmakers, Sundance can be their chance to break through in a big way. That happened last year for “Dìdi” filmmaker Sean Wang. Some films that debuted last January are still in the awards conversation, like “A Real Pain” and “A Different Man.” For actors, the festival is both a casual respite to awards season glitz (snow boots are more likely on red carpets than high heels) and can be a chance to show audiences a new dimension of their talent.

“It’s a strong year of renewal for our artist community,” Hernandez said. “And we have a lot of really great voices and stories that we get to unveil in the coming days.”

Here’s everything you need to know:

When is Sundance?

Sundance runs from Jan. 23 through Feb. 2. There are about 90 features premiering across the 11 days, with screenings starting early in the morning through midnight. Award-winners will be announced on Jan. 31.

What celebrities are expected?

Stars with films premiering include Jennifer Lopez, Benedict Cumberbatch, Diego Luna, Conan O’Brien, Alison Brie, Dave Franco, Ayo Edebiri, Olivia Colman, André Holland, Steven Yeun, Mark Ruffalo, Bowen Yang, Carey Mulligan, Joel Edgerton, Lily Gladstone, Dev Patel, Emily Watson, John Lithgow, Marlee Matlin, John Malkovich, Rose Byrne, Chloë Sevigny, Josh O’Connor, Ben Whishaw, Dylan O’Brien, Lili Reinhart and Willem Dafoe.

What are some of the big movies?

One of the greatest things about Sundance is that it’s often the under-the-radar movies that become the breakouts.

But some of the higher-profile premieres going into the festival include: Bill Condon’s “Kiss of the Spider-Woman,” starring Lopez; Ahmir “Questlove” Thompson’s documentary “SLY LIVES! (aka The Burden of Black Genius)”; “Opus,” a horror about the cult of celebrity with Edebiri and John Malkovich; Andrew Ahn’s “The Wedding Banquet,” with Bowen Yang and Kelly Marie Tran; the war satire “Atropia,” with Alia Shawkat; “Pee-wee as Himself,” about the late Paul Reubens; “Marlee Matlin: Not Alone Anymore”; and Andrew Jarecki and Charlotte Kaufman’s doc “The Alabama Solution,” about a cover-up in one of America’s most notorious prison systems.

How is the festival addressing the California wildfires?

Festival organizers have been in dialogue with filmmakers, staff, audiences and donors about the effects of the fires, supporting and accommodating where possible including pushing back deadlines to allow filmmakers more time to finish. The festival will also have a QR code displayed before screenings for information on sharing resources or contributing to relief efforts.

“As hard as the last week has been, this will be a moment to come together,” Hernandez said. “The community’s really responding to support those who need it most right now. I think that’s going to be a profound aspect of this year’s festival.”

Is Sundance really leaving Park City?

For the most part, yes. Starting in 2027 the festival will no longer be primarily based in Park City. It may stay in Utah but would operate mainly out of Salt Lake City. Other finalists are Boulder, Colorado, and Cincinnati, Ohio. The Sundance Institute is expected to announce its final decision in the first quarter of 2025.

“Park City as the home of Sundance is such a special place,” Hernandez said. “I look at it optimistically because we have two more exciting years in this current configuration. I think we’re going to make the most of those two years and make them as memorable and meaningful as we can.”

When can I watch Sundance movies?

Access to the movies premiering at Sundance doesn’t necessary require an expensive trip to Park City anymore. The festival has fully embraced an online component for many of their films.

What started as a necessary COVID-19 adjustment has become a vital part of the program. From Jan. 30 through Feb. 2, audiences can stream much of the program online. Prices start at $35 for a single film ticket and go up to $800 for unlimited access.

Otherwise, films that secure distribution can take anywhere from a few weeks to over a year to hit theaters or streaming services. Steven Soderbergh's “Presence,” which premiered last January, is just hitting theaters this week.
