Planet Outlaws
Buck Rogers (1939) re-edited from serial to feature format and re-released for theatrical distribution in 1953; an American soldier suspended in time wakes up to find himself in the futuristic world of the year 2500. Updated: I've corrected the title, it took two very obvious reviews for me to realize it should be "Planet Outlaws" not "Plant Outlaws". In my defense I am the product of a North Carolina public school.
