Irene Adler: Why are you always so suspicious?
Sherlock Holmes: Should I answer chronologically or alphabetically?
In the scene where Watson and Adler are laying out the map, they place two objects on the map to hold it down. In the very next clip where it shows Holmes talking, you see Watson and Adler placing those same objects on the map.
In the scene with the French Giant all of the French lines they speak were originally in English. Director Guy Ritchie found out that the man actually spoke French as his first language and decided on the spot to change it to add to the mystery of the film.
