What would ‘Fight Club’ look like without Brad Pitt?

David Fincher’s mind-bending 1999 psychodrama “Fight Club” (based on the Chuck Palahniuk novel of the same name) is the very definition of a cult classic. The movie was also a defining performance for Fincher's "Se7en" collaborator Brad Pitt, who played one of modern cinema's most memorable characters: Tyler Durden. But what would "Fight Club" look like without Durden?

If you haven’t seen the movie, stop reading right now because a) it’s a really great flick that you need to watch as soon as possible, and b) there are some major “Fight Club” spoilers to follow.

Starring Edward Norton as the film’s nameless Narrator and Brad Pitt as walking screw loose and pugilism aficionado Tyler Durden, “Fight Club” follows an unlikely group of men who form the movie’s titular fight club in order to let off some steam. Increasingly fed up with their daily lives, the secretive beat-'em-up society is soon doing much more than just punching one other in the face.

Spoilers: As anyone who’s seen “Fight Club” will tell you, the movie has an awesome twist ending. Pitt’s character Tyler Durden is revealed to be figment of The Narrator’s imagination. The two men are two halves of the same whole – one a boring and depressed office drone, the other an anarchist wild man. Though viewers see the movie from The Narrator’s perspective (and thus see Durden in most scenes), in reality (such that it is) whenever Norton and Pitt’s characters interact it’s really just The Narrator talking to himself and/or beating himself up.

So what if you could see that Durden-free version of “Fight Club”? An outsider's perspective on the proceedings, as it were. A video created by visual effects wiz Richard Trammell reveals just how crazy Norton’s character was by altering a key scene involving The Narrator and Durden - Their first fight. Take a look below.

As you can see from Trammell's painstakingly created video, "Fight Club"'s Narrator is absolutely certifiable from the beginning. Talking to yourself is one thing, but physically assaulting yourself? That's something else entirely. Digitally removing Durden changes the film from a violent tale of self-discovery into an to a bizarre story of mental illness, isolation, and parking lot self harm. It's what everyone but the audience saw when they watched the story of "Fight Club" unfold. Here's hoping Trammell tackles the rest of the movie to create a truly disturbing version.
