This is not a great movie, but it's a whole lot better than I expected it would be.
Roger Moore (before he was James Bond - - and, coincidentally, his character mentions ON HER MAJESTY'S SECRET SERVICE in one scene of this movie) stars as businessman Harold Pelham. After Pelham's car crashes, he is rushed to the hospital for emergency surgery. While he is on the operating table his heart stops. The surgeon is able to get it beating again . . . but the EKG shows two heartbeats.
Pelham makes a full recovery, but soon discovers that his "twin" is interfereing in his personal and business affairs. Of course, no one believes him and his family and co-workers begin to doubt his sanity.
This is like a feature-length TWILIGHT ZONE episode. Moore is good in the lead role and the Anchor Bay widescreen DVD transfer is excellent. A nice little 92 minute movie to squeeze in sometime when you aren't sure what you want to watch.
