The Man Who Haunted Himself (1970) (UK-import)
Psychological thriller adapted from an episode of the 1960s TV series 'Alfred Hitchcock Presents...'. Roger Moore stars as Harold Pelham, a successful businessman who becomes possessed by an alter-ego following a horrific car accident. This doppelganger brings chaos to Pelham's formerly sedate life: he discovers that his business has taken several drastically wrong turns, he is apparently having an affair with a casual acquaintance, and people claim to have seen him in places he's sure he has never been. This was Moore's last film before becoming James Bond in the 1973 film 'Live and Let Die'.
