Number 3: The Sixth Sense

The Plot: The third film by M. Night Shyamalan and the one that established him as “the twist guy,” The Sixth Sense is a supernatural thriller that pairs child psychologist Malcolm Crowe (Bruce Willis) with troubled boy Cole (Haley Joel Osmont), who claims he can see dead people.

The Plot Twist (Spoiler): In a reversal of The Third Man, Malcolm is dead. We saw him get shot in the opening, but just assumed he recovered. He did not.

Why It Works: Shyamalan masterfully lets us draw our own conclusions — Malcolm surived the shooting, his wife doesn’t answer him because they’re marriage is on the rocks — and lets us trick ourselves.
