Dominique Fishback says it was "extremely important" to her that her portrayal of Deborah Johnson in Judas and the Black Messiah was more than just a generic "wife" role.
Fishback plays Johnson, who was engaged to Fred Hampton at the time of his death, in the movie, which stars Daniel Kaluuya as the Black Panther Party leader and Lakeith Stanfield as FBI informant William O'Neal.
Judas and the Black Messiah is due to be released on VOD platforms in the UK from 11 March.
