Mountainfilm unveils world premiere documentaries for Telluride festival

The six world premieres Mountainfilm announced on April 23 are the kind that can fill Telluride fast: a Tom Frost portrait, a Walsh Glacier recovery story, and a caregiving-driven climb film headlined by Ethan Pringle. With the festival set for May 21 to 25 in Telluride’s box canyon, the lineup is exactly the mix that keeps Mountainfilm one of the country’s most watched mountain-story destinations.

The strongest early draws are the films that reach back into climbing history while still feeling current. Frost: The Story of a Lifetime, directed by Tom Seawell, traces legendary climber Tom Frost and the clean climbing movement, a thread that ties directly to the hardware revolution Frost helped drive in the 1960s and 1970s. Mountainfilm also put The Lost Cache on the board, following skiers and scientists as they pursue photography gear abandoned on Walsh Glacier in 1937. That cache is linked to Bradford Washburn and Bob Bates, and it was reported found in 2022 after 85 years. Strength to Weight brings the focus back to present-day pressure, following Ethan Pringle as he adjusts to family caregiving after his father suffers a stroke.

Mountainfilm’s other premieres push the same broad mountain ethic into wildfire, wildlife and working-class collapse. burn, scar looks at the aftermath of wildfire and the hard, often messy business of rebuilding. Captured examines staged wildlife photography and what it does to animals. Papertown follows a town blindsided by the closure of its paper mill. For outdoor readers, that range matters because it shows where mountain storytelling is headed now: not just summit shots and ski lines, but the human and ecological cost wrapped around them.

The festival also used the announcement to underline its own place in the outdoor calendar. Mountainfilm said it began in 1979 and has become one of America’s longest-running film festivals. It also identifies itself as an Academy Award qualifying festival in the Documentary Short Film category, which keeps Telluride relevant far beyond Memorial Day weekend. Crystal Merrill, who became festival director after the 2024 event following a national search that drew more than 50 applicants, now steers a program that still rewards both adventure and urgency.

That broader strategy shows up in the support system around the lineup. Frost: The Story of a Lifetime and Papertown were both backed by Mountainfilm’s Commitment Grant program, which awards $30,000 annually to documentary projects in production or post-production. Add in the festival’s Audience Choice Awards, Best Adventure Film, Moving Mountains, Women in Film, First Peoples, LGBTQ+ Impact and the Hilaree Nelson Lifetime Adventure Award, and the signal is clear: Mountainfilm is still the place where climbing, skiing, ecology and human consequence collide first.
