Some of my favourites: The Game Wild Things Pulp Fiction The Prestige Fight Club American History X The Departed ..... Whats yours?
A few come to mind: - Memento - Oldboy - Se7en - The Sixth Sense - The Wicker Man (no, NOT the one with Nicolas Cage. The twist in that one? It was hilarious.)
Hi, The sixth sense, The usual suspects, And of course Phillip K Dick's book and movie who's name eludes me, but where an alien android sent to Earth to destroy mankind doesn't know he's an android until the very end when he goes kaboom. Cheers,
Impostor? Based on PKD's The Impostor? I like PKD-based movies, but I like his books better. Blade Runner is excellent movie, but not exactly with a script/plot twist. Unless you figure out that Deckard is 'more human than human'...
