Is weird though because I once saw a film called Pool of London (1951)
Pool of London (film) - Wikipedia, the free encyclopedia and that film is known as the first time there was a black actor in a leading role in a UK film (even says it in the wiki)...its a great London film IIRC
Double checked if Proud Valley is a UK film and its filmed in Ealing studios and has a British producer, so seems so...
Earl Cameron,
CBE (born 8 August 1917) is a
Bermudian actor. Along with
Cy Grant, he is known as one of the first black actors to break the "colour bar" in the United Kingdom. According to
Screenonline, "Earl Cameron brought a breath of fresh air to the British film industry's stuffy depictions of race relations. Often cast as a sensitive outsider, Cameron gave his characters a grace and moral authority that often surpassed the films' compromised liberal agendas."
[1] He also had repeated appearances on many British
science fiction programmes of the 1960s, including
Doctor Who,
The Prisoner, and
The Andromeda Breakthrough.
