10 Movies You Have To Watch AGAIN To Fully Understand

David Fincher's cult hit has long been famed for its second act rug-pull that turns every event in the film on its head, so it should be no surprise that this one necessitates at least two eyes-peeled viewings.

Based on Chuck Palahniuk's book of the same name, the story follows the Narrator as he encounters an anarchist soap salesman with frosted tips and a six-pack - Tyler Durden - who pulls him out of his white collar life and into an underground world of corporate espionage, extreme male bonding and, of course, bare-knuckle fighting.

As with Shutter Island, the twist is relatively straightforward: the Narrator and Tyler Durden are the same person. And, while much of the detail is spelled out following this - we are treated to Narrator-only versions of events, where he fills the role of Durden (fighting himself in the car park, for example) - the events of the film are so significantly changed that the entire implications of what we're viewing simply can't be fully comprehended from a single viewing.

On the next watch, we scoff at how foolish we could have been, but also how cleverly layered the film is with foreshadowing and subtle actions that play into the larger themes and dénouement. In fact, this one deserves many repeat viewings, as there is always another little detail, wink or nod that slips through the cracks.
