Continuity mistake: While avoiding the glowing meteoroid, they decide to fire their jets to push them into a higher orbit. In a couple of scenes they go up but a third one has them going back down.

Continuity mistake: Mantee finds a pool of water after falling through a hole. He gets in nude, but you can see him wearing tan-colored trunks during the close-ups. However, the far away shots do show him naked.

Revealing mistake: The ground beneath Mantee's feet gives way with him falling through the hole. Boy, that hole sure looked rectangular.

Other mistake: The abandoned orbiter requires fuel to decelerate and drop out of its stable orbit. Mantee knew the orbiting spacecraft was out of fuel before leaving it, but he was still trying to give the craft voice commands to land some forty minutes into the film.

Visible crew/equipment: Paul Mantee's helmet reflects two stage lights often when he is supposedly outside.

Trivia: The alien ships look almost like the Martian ships from the movie War of the Worlds minus the wires. However, they were neat to watch. Byron Haskin directed both Wars of the Worlds and Robinson Crusoe On Mars; thus, that is why they have the same spaceships.

Trivia: Paul Mantee was the main star of this movie and Adam "Batman" West was seen for several minutes at the beginning and the middle of the movie. Two or three years later, Adam West was the main star in Batman and Paul Mantee was one of Catwoman's (Julie Newmar) henchman.
