I'd make a bad detective, admits Sherlock Holmes actor

Robert Downey Jr was joined by an all-star cast at the European premiere of his new film, 'Sherlock Holmes: A Game Of Shadows' - but the leading man admitted he would make a lousy detective.

The US actor reprises his role as the famed sleuth in the crime caper - the sequel to 2009 box office hit Sherlock Holmes - which sees his character reunite with friend Watson to battle criminal mastermind Professor Moriarty.
