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."
 Imruh Bakari worked with Shabazz and co-founded Kumba productions with him.
Playing Away is a 1987 TV comedy film directed by Horace Ové, from a screenplay by Caryl Phillips.
 In the story, an English cricket team, fictitiously named "Sneddington" (based in Lavenham, Suffolk), invites a team of West Indian heritage based in Brixton (South London) to play a charity game in support of their "Third World Week."
 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".
Zoot Suit is a 1981 film adaptation of the Broadway play "Zoot Suit".
 Both the play and film were written and directed by Luis Valdez.
 The film stars Daniel Valdez, Edward James Olmos — both reprising their roles from the stage production — and Tyne Daly.
 Many members of the cast of the Broadway production also appeared in the film.
 Like the play, the film features music from Daniel Valdez and Lalo Guerrero, the "father of Chicano music."
Pressure is a 1976 British drama film and the first feature-length fiction film directed by a Black film-maker in Britain.
 Directed by Horace Ové, and co-written by him with Samuel Selvon, "Pressure" is a powerful portrait of inter-generational tensions between first- and second-generation West Indian migrants in London's Notting Hill area.
 According to Julia Toppin,
Zoot Suit is a play written by Luis Valdez, featuring incidental music by Daniel Valdez and Lalo Guerrero.
 "Zoot Suit" is based on the Sleepy Lagoon murder trial and the Zoot Suit Riots.
 Debuting in 1979, "Zoot Suit" was the first Chicano play on Broadway.
 In 1981, Luis Valdez also directed a filmed version of the play, combining stage and film techniques.
Horace Ové, CBE (born 1939), is a British filmmaker, photographer, painter and writer, one of the leading black independent film-makers to emerge in Britain since the post-war period.
 Ové holds the "Guinness World Record" for being the first black British film-maker to direct a feature-length film, "Pressure" (1975).
 In its retrospective history, "100 Years of Cinema", the British Film Institute (BFI) declared: "Horace Ové is undoubtedly a pioneer in Black British history and his work provides a perspective on the Black experience in Britain."
Visions is a 90-minute American television weekly anthology series that aired from 1976–80.
 It was produced by KCET in Los Angeles and televised nationally on PBS.
 It concentrated on the works of mostly new and some prominent writers, including Cormac McCarthy, Marsha Norman, Jean Shepherd, Luis Valdez, and Robert M. Young (director).
 Each episode was written by a different writer and starred a different cast.
Zak Ové (born 1966) is a British visual artist who works between sculpture, film and photography, living in London, UK, and Trinidad.
 His themes reflect "his documentation of and anthropological interest in diasporic and African history, specifically that which is explored through Trinidadian carnival."
 In work that is "filtered through his own personal and cultural upbringing, with a black Trinidadian father and white Irish mother", he has exhibited widely in Europe, the United States and Africa, participating in international museum shows in London, Dakar, Paris, Dubai, Prague, Berlin, Johannesburg, Bamako and New York City.
 His father is the filmmaker Horace Ové and his sister is the actress Indra Ové.
The Orchid House is a four-part television serial that first aired on British television's Channel 4 from 21 February to 14 March 1991, directed by Horace Ové.
 Its cast featured Diana Quick, Madge Sinclair, Nigel Terry, Elizabeth Hurley, Kate Buffery and Frances Barber, and was based on Phyllis Shand Allfrey's only novel of the same name.
Luis Valdez (born June 26, 1940) is an American playwright, actor, writer and film director.
 Regarded as the father of Chicano theater in the United States, Valdez is best known for his play "Zoot Suit", his movie "La Bamba", and his creation of El Teatro Campesino.
 A pioneer in the Chicano Movement, Valdez broadened the scope of theatre and arts of the Chicano community.
