Coldplay's Chris Martin suggested Stephen Fry for a role in 'Sherlock Holmes: A Game of Shadows'.

Director Guy Ritchie cast the British star as Sherlock's intelligent brother Mycroft in the sequel, and he admits it was Chris -a fan of the fictional detective - who suggested him for the part.

Guy said: "Robert Downey Jr. and I have a mutual friend, that chap Chris Martin out of Coldplay, and he is a Sherlockian - very enthusiastic about the whole thing, as is Stephen Fry - and it was his idea, I think he told Robert first."

Robert added: "Every good idea in this movie came from Chris Martin."

Despite playing the highly intelligent character, Stephen appears nude for a section of the film, something which Guy believes may have been entered into The Script by the man himself.

He added to BANG Showbiz: "He turned up, on the day, naked. There was no great resistance - rather like getting Robert into a dress - no great resistance. I've got a sneaking suspicion it could have been his idea, to turn up without any clothes. There was no work on my part."
