An anniversary screening of ‘Little Miss Sunshine,’ was one of the festival’s biggest hits. The last Sundance Film Festival in Utah is drawing to a close this weekend.The Park City gathering was a wistful farewell to the place Robert Redford’s brainchild has called home for over 40 years and launched so many careers. Although the festival isn’t ending — it will start anew in Boulder, Colorado, in 2027 — it did have many, from filmmakers to volunteers, feeling nostalgic about the change whether their Sundance story began in 2022 or 1992.A Wednesday night anniversary screening of “Little Miss Sunshine,” still one of the festival’s biggest hits, was an especially emotional affair as filmmakers Jonathan Dayton and Valerie Faris, and actors Toni Collette, Greg Kinnear, Paul Dano and Abigail Breslin, gathered once more, 20 years later, at the festival’s most famous and largest location, the Eccles Theater. Many in the audience had seen the movie and some had even been at the 2006 premiere. But a fair number were experiencing it for the first time and the response was rapturous.“Who would have imagined that a single film could deliver two electric nights at a Sundance Film Festival?” said festival director Eugene Hernandez.It wasn’t all looking back, however. The festival’s program is first and foremost about discovery. First time feature filmmakers comprised about 40% of the slate. The programmers also wanted to do right by Park City.“I feel like we achieved that based on what we’ve seen this week,” said Sundance programming director Kim Yutani. “The enthusiasm for the artists that we have now shared with the world is significant. It’s profound.”
