But I noticed at least 3 instances where I saw something flash into the picture for a split second. The first occurred in the hospital when Ed Norton got beaten the first time, and the doctor is telling him to get some exercise.

does it have anything to do with Brad Pitt's character, or is Fincher just being weird?

anyone else notice it?

tell me I'm not losing my mind.

Np -- Snow Falling on Cedars, "Tarawa" is one of THE coolest ever choral tracks

SPOILER AHEAD IF YOU'VE NOT SEEN THE FILM!!!

I look on it as the beginnings of the split-personality that Norton's character is about to endure. The times that Durden appears are times when Norton's character COULD choose to do something else i.e. like Durden WOULD do.

It does, in a way, reference, Durden's penchant for splicing in porn frames into other films, but that one is part of the narrative and Durden appearing is prolly Fincher's (or the writer's) handiwork.

I think it happens four times in the movie. As pointed out above, it's always exactly one frame with Tyler Durden. Didn't notice it in the cinema, but later I read about it and immediately saw it when watching the fantastic DVD. Everytime this happens, can Edward Norton looks especially absent and a bit annoyed. Right before the end credits, there's a more hard-core version of this flash effect.
