Hilarious crime comedy notable for being the comebacks for both Robert Downey Jr. & Shane Black to cinema greatness. Downey is superb as Harry Lockhart, hilariously fumbling his way through the crime caper while proving what a great actor he is (reportedly, it was this performance that convinced Marvel to cast him as "Iron Man"). He is paired perfectly with Val Kilmer as Gay Perry, a openly homosexual detective forced to keep Harry from killing himself while trying to solve the murder. Behind the camera, Shane Black crafts a hilarious send up to crime movies, mocking everything from the voice over narrative (Downey excels at this as well) to the cliched twists. However, it is not an full on satire and there are moments of real drama (when Harry is forced to see someone die before his eyes, it leads to a pretty powerful moment). Overall, one of the funniest crime comedies in recent years, and since it's Shane Black, a darn fun Christmas movie.
