Burning an Illusion: Burning an Illusion is a 1981 British film written and directed by Menelik Shabazz, about a young British-born black woman's love life, mostly shot in London's Notting Hill and Ladbroke Grove communities.  It was only the second British feature to have been made by a black director, following Horace Ové’s 1975 "Pressure", and is described by Stephen Bourne as "the first British film to give a black woman a voice of any kind."

Playing Away: Playing Away is a 1987 TV comedy film directed by Horace Ové, from a screenplay by Caryl Phillips.

According to Screenonline, "The gentle comedy of manners and unexpected reversal of white and black stereotypes in "Playing Away" contrasts sharply with the stylistic experimentation and the militant denunciations of racial prejudice in director Horace Ové's earlier feature, "Pressure" (1975)." " New York Times" reviewer Vincent Canby called it "witty and wise without being seriously disturbing for a minute".
