He made audiences hoot with laughter, but behind the naughty jokes and funny mannerisms, Carry On star Kenneth Williams was deeply unhappy. Tonight, the South Bank Show starts its new run with a fascinating film about the complex comedian's life, featuring clips from his films and excerpts from his diaries. Although he was almost a British institution, Kenneth Williams who died in 1988, lived as a recluse and was tortured by problems about his sexuality. Written and presented by Melvyn Bragg, the show includes contributions from Kenneth's closest friend and co-star Barbara Windsor, actress Fenella Fielding and Barry Took.
