(Original stars Robert Downey Jr. and Jude Law are returning to play the title detective and his trusty sidekick Dr. Watson, respectively, with The Girl with the Dragon Tattoo star Noomi Rapace taking McAdams’ place as the main female lead. Mad Men‘s Jared Harris is playing the infamous Sherlock Holmes nemesis Professor Moriarty.) No details were provided on what McAdams’ character Irene Adler is up to in the film. See a shot of McAdams on the set, as well as footage of stunt men being sent flying (always fun), in the video below:
