Life’s Essentials with Ruby Dee, a documentary about the iconic Ossie Davis (1917-2005) and Ruby Dee (1922-2014) by their grandson Muta’Ali, will have its world premiere at Film Life’s 18th annual American Black Film Festival on Sunday, June 22 in New York City. The film—part tribute, part history lesson and part coming-of-age story—give viewers an intimate look into the remarkable lives of the couple many consider the all-time king and queen of Black Hollywood.

Stunned by the death of his grandfather, Muta’Ali moves to New York to be able to spend more time with his grandmother and get answers to some of his burning questions. The film follows him as he delves into chapters of their lives that span both the 20th and 21st centuries, posing probing questions to his grandmother as well as to celebrity friends, costars and fellow activists of the star couple in his search for his own life’s path.
