Nigerian-American filmmaker, Chinonye Chukwu, has become the first Black woman to win the Sundance Film Festival’s Grand Jury Prize for her U.S. Dramatic entry, Clemency.

According to Indiewire, Chukwu was part of an already banner year at the festival, with all the four jury prizes going to women.

But Chukwu had additional acclaim in being the first Black woman to win the Grand Jury Prize — the festival’s highest honors, as voted on by individual juries — for her category.

The filmmaker both wrote and directed the death row drama.
