Rocketship X-M (1950) was the second of the American science fiction feature films of the space adventure genre begun in the post-war era, in 1950. Because expensive special effects and production value delayed the release of Destination Moon, this black-and-white film from Lippert Pictures was quickly shot (in 18 days) so as to be able to make it to the cinemas first with the story of a moon expedition that instead lands on Mars.
"The Green Man" is penciled and and inked by Al Williamson and is reprinted from World of Suspense (Marvel, 1956 series) #3 (August 1956). Synopsis: Some force on the moon turns an astronaut's face green for twenty-four hours.
