The Boulder International Film Festival returns next weekend with “Ezra” (7:30 p.m. March 1), featuring Robert De Niro and real-life partners Bobby Cannavale and Rose Byrne. It’s a cross-country, generational family dramedy about what’s best for a mildly autistic, 11-year-old boy.

The closing spotlight film is “The Cowboy and the Queen,” a documentary about old-time California rodeo cowboy Monty Roberts, who pioneered how to train horses nonviolently – and he shared a 30-year friendship with Queen Elizabeth II.

The fest’s signature “Adventure Film Pavilion” brings director James Erskine for the Colorado premiere of “Copa 71” (12:30 p.m. March 2). The film, produced by Serena and Venus Williams, chronicles a watershed women’s international soccer tournament in Mexico City in 1971. 

Other highlights include two world premieres. “Arctic Ascent with Alex Honnold “ (2:30 p.m. March 1) follows the famed free-solo climber as he scales a previously unclimbed sea cliff in Greenland to research a key climate-change bellwether that could impact the entire planet. “Nothing’s for Free” (8 p.m. March 2) is the true story of the birth and legacy of freeride mountain biking.
