10. The Norton Flip-Flop - Primal Fear
Edward Norton delivers a masterful, Oscar-nominated performance asAaron Stampler, the seemingly shy and retiring altar boy who ends up being accused of murdering an archbishop. It's Norton's searing turn that keeps us on edge, preventing us from twigging the sublime twist ending to Gregory Hoblit's cracking thriller, in which it turns out that, yes, Aaron was the bad guy all along.
Over the course of the film, we learn that Aaron has a second personality called Roy who appears to have caused the murder, yet at the film's climax, we learn that Roy - or in fact, Aaron - never existed, and that Norton's character simply concocted an elaborate lie, such that he would spend a few months in an asylum and then end up back on the streets soon enough.
Twist endings can feel cheap and forced, but Primal Fear's works because while it's a swerve, it's also backed up by not only Norton'scommandingperformance, but a live-wire script that, surprisingly, doesn't feel convoluted.
