The premise of Split might seem pretty unique, but the deeply unsettling idea of multiple personalities crept into cinema long before M. Night Shyamalan tackled the topic.
While Shyamalan's take might set itself apart with the extreme and murderous nature of the antagonist's fractured mind, below are some other movies who also dip their toe into the split personality pool.
Be warned, minor spoilers lie beneath, but I have tried to keep the crucial twists as vague as possible so the plots still pack a punch.
