So, I'm watching The Machinist last night and throughout the film the lead character is slowly filling in a hangman puzzle - it's most curious, possibly the key to a large chunk of the film. What could it be?

CUT TO ADVERTS: up pops the "Late Night Films" trailer which happily includes a flash of the completed puzzle, presumably to save us the hassle of thinking about it for too long.

Thanks Film4 trailer editor! Most useful. Next time it would be useful if you could also tell me who Keyser Söze is via the medium of trailer, save me wondering throughout the Usual Suspects who it is.
