“Nanny,” from writer-director Nikyatu Jusu and starring Anna Diop and Michelle Monaghan, won the Grand Jury Prize in the drama category for its depiction of a Senegalese immigrant working for a wealthy family in New York City. The top jury prize for documentary went to Ben Klein and Violet Columbus for “The Exiles,” in which a documentary filmmaker attempts to finish a film she started in 1989 after the Tiananmen Square massacre.

“Navalny,” a late, secret addition to the competition, won the documentary audience award and the festival favorite award. Daniel Roher’s thrilling film tracks the Russian opposition leader as he recovers in Berlin after being poisoned.

“Today’s awards represent the determination of visionary individuals, whose dynamic work will continue to change the culture and create discourse throughout the year,” said Joana Vicente, Sundance Institute CEO. “This year’s entire program has proven that no matter the context, independent storytelling remains a pivotal tool in expanding critical dialogues, and these stories will and must be shared.”

Several of last year’s Sundance award winners remain in the Oscars conversation, including “CODA,” “Flee,” “Hive” and “Summer of Soul.”

The award-winning films will screen on the Sundance online platform on Saturday and Sunday. Tickets will go on sale starting at 7 p.m. Eastern on Friday.

“Whether you watched from home or one of our seven satellite screens, this year’s Festival expressed a powerful convergence; we were present, together, as a community connected through the work,” said Tabitha Jackson, the director of the Sundance Film Festival. “And it is work that has already changed those who experienced it.”
