AS HOLLYWOOD EVENTS go, there are few more congratulatory than film festival awards ceremonies, where everyone wants to cheer for the Next Big Thing before they get huge. Yet, at this year’s Sundance Film Festival, the biggest applause at the awards show wasn’t for a director or actor—it was for Rachel Morrison, a director of photography on the festival jury. “Earlier this week,” host Jason Mantzoukas said while announcing her name, “she became the first woman ever to be nominated for the Academy Award for cinematography. Her historic nod is for last year’s Sundance hit Mudbound.” Out in the audience, Morrison smiled sheepishly; at her side, fellow jurors Jada Pinkett Smith and Octavia Spencer whooped up a storm. The audience stood to clap.
