A drama about the life of entertainer Kenneth Williams is to be broadcast on BBC Four next year.
Kenneth Williams' diaries were published after his death
The Carry On star, who also appeared in a number of TV, radio and stage shows, will be profiled in Fantabulosa.
Actor Michael Sheen will play the troubled star in the 80-minute drama based on Williams' own diaries.
BBC Four controller Janice Hadlow said: "I can't think of a more suitable actor than Michael Sheen to take on the iconic role of Kenneth Williams."
She added: "I just know that he will do credit to the late, great performer."
Williams, best known for his 22 appearances in the Carry On films alongside stars like Sid James and Barbara Windsor, first came to prominence in the 1950s working alongside Tony Hancock.
He epitomised camp British humour, but behind his cheery demeanour was a troubled man who struggled to form relationships.
Williams died in 1988 from an overdose of barbiturates. It was never clearly established whether he committed suicide or if his death was accidental.
