Tony Stark and Mr. Napkin Head walk into a bar. What happens next? Throw in some slow motion punches and boom, you've got a franchise from the mind of Guy Ritchie, featuring Robert Downey Jr.and Jude Law. Ritchie’s 2009 crack at Arthur Conan Doyle’s detective is still his most successful mainstream hit — and the only film of his that ever managed to cough up a theatrical sequel. Now both Sherlock Holmes and Sherlock Holmes: A Game of Shadows are coming to Netflix on September 1. If you’ve forgotten how much fun Downey Jr. and Jude Law were together, this is your chance to get reacquainted.
