I haven't seen this movie yet but this Saul Bass-inspired opening title sequence for Kiss Kiss Bang Bang is pretty sweet. What else would you expect from the people who brought you the Six Feet Under title sequence.

One thing I don't see mentioned very much is that the phrase originates from what the Japanese used to call James Bond - Mr. Kiss Kiss Bang Bang. Very apt description if you ask me. If I was Cubby Broccoli's family, I'd be defending the trademark on that for all it was worth.
