He continued in British films during the 1960s, portraying stereotypical roles, such as a butler in the film Woman of Straw (1964), and in other films, such as East of Sudan (1964), Khartoum (1966) and The Last Safari (1967). He also appeared on television, in programmes such as The Human Jungle (The Twenty-Four Hour Man, Series 2 Episode 3) first aired 26.10.64 playing Alvar Bell, Z-Cars, Dixon of Dock Green, Gideon's Way, Danger Man, and a 1968 episode of The Avengers. In 1968, he also played the lead role in a West End production of Night of Fame. According to his obituary in The Times, this was the first time that a black actor had played a role written for a white man in English theatre. He was seen as a British equivalent to Sidney Poitier, and was frustrated that actors who started out at around the same time as him – such as Sean Connery, Terence Stamp, Michael Caine, Tom Courtenay and John Hurt – had become stars, and he had not.
