Ed Nelson "played" the crab monster with Beach Dickerson operating the monster's claws.

Allied Artists Pictures released this film on a double bill with Not of This Earth (1957) to many drive-in theaters with the tag line "Terrorama! Double Horror Sensation!"

A scene involving two pilots was shot, but cut from the final finished film.

When the scuba divers are rising to the surface (from the underwater camera shot), the water depth appears to be over 25 feet, yet when the camera angle changes to above, the divers immediately stand up after surfacing.

When Deveroux calls out to the first team upon arriving at the island, the echo does not match what he shouts.

Depictions of earthquakes are accomplished by merely shaking the camera. While the scientist group moves about when the earthquake strikes, the sailor group doesn't move around at all.

Seaman Jack Sommers: But this is the second bunch of brains to come out here. What happened to the first?

Hank Chapman: What does it mean, Doctor?

Dale Drewer: Hank!... He gave his life...
