Infernal Affairs (2002)
The Hong Kong original of Scorsese’s The Departed, but prepare to get confused in this thriller. A mole in the police and an undercover cop hanging about with a triad try to work out each other’s identities at the same time. Infernal Affairs is a smart world cinema flick that keeps you on edge while you desperately attempt to decide who to cheer for.
