Radio Times review

Considering he's possibly the world's most charming man, Stephen Fry is never too far away from controversy. The publication of the third volume of his memoirs, More Fool Me, was accompanied by a racket as some readers and commentators demanded he be retrospectively prosecuted for his acknowledged cocaine use in the 1980s.

But Fry was determined to tell what he's described as the "ugly truth" about his drug-taking past that even saw him snorting cocaine during a reception at Buckingham Palace. "I was an imbecile, an idiot, I got caught up in a ridiculous dependency," he told Huw Edwards recently.

Another man who's had his own monumental battles with addiction, Robert Downey Jr, joins Fry and Oscar-winning Robert Duvall on the Norton sofa.
