Flight to Mars is a 1951 American Cinecolor science fiction film drama, produced by Walter Mirisch for Monogram Pictures, directed by Lesley Selander, that stars Marguerite Chapman, Cameron Mitchell, and Arthur Franz.

[1] The film's storyline involves the arrival on the Red Planet of an American scientific expedition team, who discover that Mars is inhabited by an underground-dwelling but dying civilization that appears to be humanoid.

The Earth crew are taken to a vast underground city, which is being sustained by life-support systems fueled by a (fictional) mineral called Corium, from which the Martians extract water and air, and generate energy.

Additionally, Flight to Mars postulates a humanoid species which is superior, in many ways, to humanity, and may possibly pose a long-term, strategic threat.

[5] Variety wrote: "Presentation is on a standard level, with stock situations and excitement, but physically film looks better than the usual light budgeted effort through a well-conceived production design that displays technical gadgets and settings nicely.

Lesley Selander's direction of the Arthur Strawn screenplay keeps it moving along at a fairly good pace, although surfeit of dialog occasionally slows it down.

"[6] The Monthly Film Bulletin wrote: "A science fiction adventure on the comic strip level, with dialogue, playing and use of colour to match.

The technical effects are poorly managed, with little attempt to sustain any illusion, and Mars itself looks like a futuristic Ideal Home Exhibition run up in cardboard.
