(Spoiler Alert – Skip down to last paragraph to avoid spoilers and read recommendation)
Andre and François Delambre are two brothers who own a technology company. Andre is a genius and he is working on a teleportation machine. He shows it to his wife Helene but she notes that the machine still has some problems. When Andre thinks the machine is perfected, he tries to teleport his cat but it disappears. Finally, after much work, he shows his wife that it can teleport a guinea pig successfully. Next, he plans to teleport himself.
The next day Andre’s little son catches a fly with a white head in the garden with his butterfly net. Helene makes him release it. When Andre does not appear for dinner Helene goes down to his laboratory. But the door is locked and Helene finds a typewritten letter from Andre saying his experiment has gone awry. A fly entered into the chamber and during the teleportation the fly got a human arm and head and Andre got the head and leg of a fly. He could still think like a human but he was finding his mind slipping away. He tells Helene to catch the fly so that he can go through the teleporter with it and hopefully return to normal. They catch the fly but it escapes again. Andre despairs and tells Helene (through writing on a blackboard) that he will destroy his dangerous machine and his notes. And he wants to die so he tells Helene to assist him by crushing his head and arm in the hydraulic press in his lab to destroy the evidence of his horrible accident. She agrees. After helping her husband to suicide she calls her brother-in-law François (played by Vincent Price) who calls police inspector Charas. When they arrive, Helene tells them how she killed her husband. Later on, after much coaxing she tells them the story of the fly. But they assume she has gone mad. Inspector Charas gets a warrant for her arrest for murder. But just before she is taken away Andre’s son tells François that he has found the fly in a spider’s web. François calls Charas to the web and they see the fly with its human head and hand and hear it cry for help as the spider comes to devour it. Charas crushes the spider and its victim with a rock and is horrified by the reality of Helene’s story. Charas and François figure a story involving Andre’s suicide to protect Helene. The movie ends with François assuming the guardianship over Andre’s wife and son.
I saw this movie as a child on tv. And then, as now, the big scene in this movie is the spider web scene. The pathetic little voice coming out of the haggard face of the fly is horrifying as we see the enormously magnified head of the spider come closer and closer to the poor trapped fly. The other notable scene is where Helene pulls off the hood hiding Andre’s head and we see his repulsive fly face. It’s kind of hard to see it. It seemed out of focus but it was reasonably hideous and Helene screams to very good effect. The only decent acting was done by the police inspector. The rest of the cast acted their lines but no Academy Awards were earned. Vincent Price gave his usual over the top delivery. One surprise for me was that the actor who played Andre was David Hedison and I recognized him as the captain on the 1960’s television series “Voyage to the Bottom of the Sea” about a US Navy submarine that was always bumping into giant squid and other under sea monsters. This movie is for connoisseurs of campy giant insect sci-fi films. It’s not as good as “Them!” but it’s still fun for fans of this type of movie.
