Guy Ritchie has revealed that the physical work that the actors had to do on Sherlock Holmes: A Game of Shadows was huge.
Ritchie is back in the director's chair for a second Sherlock Holmes movie, coming two years after the first.
The movie reunites him with Robert Downey Jr and Jude Law, who reprise the role of Holmes and Dr Watson, and he reveals that they had to do a lot of physical work.
The first movie was a box office hit when it was released back in 2009 and Downey Jr went on to pick up a Golden Globe for his central performance.
This time around there are a whole host of new faces on the cast list including Noomi Rapace and Jared Harris as Moriaty.
Sherlock Holmes: A Game of Shadows is released 16th December.
