The was a British film portraying a stage actor who is hit on the head during a bombing in World War II raid on London and then acts the "strangler" in the play he's in, forgetting that he's just an actor. It's an interesting premise. Most of the plot was pretty obvious but there was a twist or two thrown in which kept my attention.
However, to be honest, after about 40 minutes my mind started to wander, as the movie just plodded along. A story about a guy with "multiple personalities," so to speak, someone who can't distinguish anymore between fact and fiction, and winds up thinking he's "the Brighton Strangler" should have been a lot more interesting than it was. At 67 total minutes, there is no excuse for this to be a boring movie.
John Loder is good in the lead as "Reginald Parker/Edward Gray," but the story doesn't live up to his performance. It just sags, big-time, in that middle section. There are major plot holes in here, too. The guy plays a "famous" actor yet no one recognizes him. I bet if someone re-made this story, it could a chilling one.
