Robert Downey Jr has revealed that he loves Sherlock Holmes' dependency on Watson.
The actor returns as the super sleuth this week two years after he won a Golden Globe for his performance in the first movie.
He once again teams up with Jude Law, who plays Watson, and filmmaker Guy Ritchie for Sherlock Holmes: A Game of Shadows.
This is the first movie role for Downey Jr since comedy Due Date late last year and the movie looks set to be bigger and better than first time around.
He will be returning to the role of Tony Stark next summer as he joins Chris Hemsworth, Chris Evans, Jeremy Renner and Mark Ruffalo in The Avengers.
Sherlock Holmes: A Game of Shadows is released 16th December
