The alien monster is the same one featured on the cover of the album "Walk Among Us" (1982) by The Misfits.

$54,000 - or just over a quarter of the film's budget - was spent turning the footage into the so-called Cinemagic process.

The "Cinemagic" process, used for all scenes on the surface of Mars, was the result of an attempt by producer Norman Maurer to turn live-action footage directly into hand-drawn animation - or to simulate that. This would enable hand-drawn backgrounds to look as real (or as unreal) as the live action footage. It didn't have that effect here, of course. See The Three Stooges in Orbit (1962) for Maurer's second (and failed) attempt at the same process.

When leaving the ship, the crew's space helmets lack protective glass.

Les Tremayne clearly states that have deliberately landed on the equatorial area of Mars because that area is most likely to have life. Later Jack Khruschen, clearly contradicting that geography, asks where the polar caps are.

We are left to assume that four trained scientists - one of whom comments that its leg-shaped "trees" are at least 40 feet high - fail to notice the rat-bat-spider-crab monster standing in the midst of an otherwise empty plain.

CWO Sam Jacobs: All right, everybody! Come and get it! Breakfast's ready! Hot coffee, hard tack and vitamin pill!

Prof. Theodore Gettell: It takes a brave man to admit his fears, Sam. We're all afraid of the unknown.

Maj. Gen. George Treegar: The hell with radiation. Let's go.
