They don't have a clue.
Directed and written by Etan Cohen (Get Hard), Holmes & Watson is a 'humorous take on Sir Arthur Conan Doyle's classic mysteries'. Will Ferrell (Elf) and John C. Reilly (Step Brothers) reunite alongside Ralph Fiennes (Harry Potter), Rebecca Hall (Christine) and Kelly Macdonald (Brave). After the Queen's life is threatened, Sherlock Holmes and John Watson must stop Moriarty's master plan. Step Brothers has become a classic - are Ferrell and Reilly the secret to comedy gold?
