Doppelganger, aka Doppelganger: The Evil Within (1993) is a straight-to-vid horror thriller staring Drew Barrymore as a girl who moves from New York to LA after the brutal murder of her mother, which she is suspected of. She rents a room from wannabe writer George Newbern. He learns of her belief that she has a doppelganger, an evil alter ego that killed her mother and is after her. Her shrink follows her to LA, and there is a brother who was accused of killing his father, or was it the brother's doppelganger that killed the father? Or was it Drew? Or Drew's doppelganger? Or was it the shrink, who pretended to be everyone's doppelganger because he had the hots for Barrymore?

Or maybe I was the Doppelganger ...

This is one of the more muddled films I have sat through lately. The film is too convoluted to care much about, and the properties of a doppelganger seemed to get redefined after each day of shooting, when they looked at the footage.
