Sherlock Holmes, 2009.
In the stories, Holmes is described to be an expert in Baritsu. In the film, however, the martial art that Holmes used is the Wing-Chun Kung Fu (famously used by Ip Man Yee and Bruce Lee). Robert Downey, Jr. is a practitioner of the art in real-life, and the fight scene between him and David Garrick at Punch Bowl Pit was coordinated with the help of his trainer.
Director of photography Philippe Rousselot used a special high-speed digital camera specifically to film the Punch Bowl fight sequence. The key moment where Holmes punches his opponent's jaw was filmed one second in real time, and turned into a seven-second shot without additional post-production aid.
Rachel McAdams, Jude Law, and Robert Downey Jr. reportedly did most of their own stunts.
