La mosca

In a Montreal machine shop, scientist Andre Delambre (Al Hedison) is found crush to death with his wife Helene (Patricia Owens) at the controls. She calls to confess to his brother Francois (Vincent Price). With the head crushed, Francois identifies the body with a long scar on his leg. Helene's confession seems suspicious and Andre's basement lab is trashed. Helene seems obsessed with flies and Francois pretends to have captured a white-headed fly. Helene recounts the story to him and Inspector Charas. Andre had succeeded in making a teleportation device.

This is much better than a simple 50's B-movie. The story is actually quite compelling. The acting is relatively good. Vincent Price is playing it straight. The production looks good. The directions are a little stiff which is the style of the day. It is still the story that is so great and the reveal is absolutely iconic.
