Chris’s review published on Letterboxd :
Recently deceased Roger Moore considered this his best performance, which was what prompted me to give it a look. About a man who can’t explain why there is a duplicate of himself. A thriller that does a good job of building suspense by not revealing the mystery. Like the audience, Moore’s character Harold Pelham is in the dark and trying to find answers. You can definitely see why he was picked for Bond a few years later, Pelham has a similar presence and humor to Moore’s 007. He is not the most versatile, and the bowler hats are a bit dated now, but a screen actor I enjoy watching.
