10 Movie Endings You Can Only Work Out For Yourself

10. Martha Marcy May Marlene

Martha Marcy May Marlene stars Elizabeth Olsen in her stellar film debut as Martha, a young woman who has been living with a cult for two years and, upon deciding to leave, struggles to pull herself away entirely.

Even when exiting the cult and living with her sister Lucy (Sarah Paulson), Martha has PTSD-induced delusions that the cult's members are pursuing her, leading to a climax where Martha finally agrees to be taken to a mental hospital.

As Lucy and her husband Ted (Hugh Dancy) drive Martha there, however, Martha notices a man she spotted earlier in the day get into his car and seemingly follow them. Martha looks out the back window of the car and then the film just... ends.

The whole point of Martha Marcy May Marlene is its ambiguity, namely that Martha is an unreliable narrator and we as the audience have no idea if her perspective is correct or delusional.

Whether you believe she's reacting to a fantasy or is indeed being followed by the cult, they're both completely valid readings sufficiently backed up by everything leading up to that point.
