Downey Jr's grumbles over 'Sherlock' shooting schedule

Robert Downey Jr. was "grumpy" when he first started shooting 'Sherlock Holmes: A Game of Shadows'.

The 46-year-old actor - who reprises his role as Arthur Conan Doyle's legendary detective in the second film in the franchise - enjoyed the "brutal" schedule of the first movie, and was disappointed the action shots were left to the end in the second instalment.
