Other films with twisted plots
This is one of those films where you can't give away a general synopsis to anybody without spoils big twists that come early in the film. Other films - mostly thrillers - that come to mind would be:
Psycho (even though people have been spoiled on that one already)
Gone Girl
The Place Beyond The Pines
In the Bedroom
Side Effects
Les Diaboliques
Vertigo
Mulholland Drive
The Talented Mr. Ripley
My mind's kind of limited right now. I know there's more than this list. Does anyone know of films of that sort, without revealing its big narrative changes?
