The juries for the the 2018 Sundance Film Festival will be some of the most diverse ever, with three women — two of them African-American — on the five-member U.S. Dramatic competition jury.

Actors Octavia Spencer and Jada Pinkett Smith will be joined by cinematographer Rachel Morrison, actor Michael Stuhlbarg and director Joe Swanberg on the U.S. Dramatic jury, festival organizers announced Tuesday. People of color also are in the majority on the U.S. Documentary jury and prominent in other juries.

Seven juries will decide the award winners at Sundance, which starts Thursday night in Park City and runs through Jan. 28 at venues in Park City, Salt Lake City and the Sundance resort.

Winners will be announced at an Awards Night ceremony on Saturday, Jan. 27, at the Basin Fieldhouse in Kimball Junction. Emceeing the ceremony is actor-comedian Jason Mantzoukas, currently appearing on “The Good Place” and “Transparent” and starring in the Sundance premiere “The Long Dumb Road.”
