Actor David Harewood shares his impressions of John Elliot’s game-changing 1956 BBC drama, which explored the challenges and racism encountered by Windrush immigrants from the West Indies, who had come to Britain after being promised work and a secure future. David discusses the impact A Man From the Sun still holds today, the performances of cast members Errol John, Cy Grant and Earl Cameron, and the context and attitudes of a decade that saw the BBC bring viewers issue-led dramas like this while at the same time creating series such as The Black and White Minstrels.
