Flying Disc Man from Mars is a 1950 Republic Pictures 12-chapter black-and-white science fiction adventure film serial, produced by Franklin Adreon, directed by Fred C. Brannon, that stars Walter Reed, Lois Collier, Gregory Gaye, James Craven, Harry Lauter, and Richard Irving.

Mota, having been shot down by an experimental ray gun, blackmails American scientist, and former Nazi, Dr. Bryant (James Craven) into assisting him and hires some criminals to be his henchmen.

Kent Fowler (Walter Reed), the private pilot who shot down Mota with Dr. Bryant's ray gun, gets caught up in these events while working security for atomic industrial sites.

[5] Other stock footage from several earlier Republic serials was reused to pad out Disc Man in order to lower its production costs.

This includes the rocket crash from The Purple Monster Strikes, a car chase from Secret Service in Darkest Africa, and various scenes from G-Men vs. the Black Dragon.
