A railroad passenger car carrying a reporter and his photographer mysteriously breaks away from its locomotive, accidentally ending up on a remote sidetrack in Gudavia, an isolated Ruritanian-style, one-village dictatorship. The newsmen discover a mad scientist using gamma rays to turn the country's youth into either geniuses or subhumans.
In June 1951, Irving Allen announced he would make The Gamma People in Austria with Brian Donlevy and Virginia Grey. It was based on a screenplay by Oliver Crawford and a story by Louis Pollock. Allen said the script was about German scientific experiments during the war which caused cells to mutate. He said he had finance from the United States and Austria.[9] Allen did a location trip to Austria in July.[10]
In December 1951 Allen announced he had formed Warwick Productions with Albert Broccoli, but that he still intended to make The Gamma People with Robert Aldrich.[11]Dick Powell was slated to star.[12]
The film would not be made for another three years. Paul Douglas was cast in the lead and Warwick wanted Trevor Howard to co-star.[13][14] Filming took place in Austria in July 1955. Patricia Medina was meant to co-star, but then was called in for another commitment, on a Sam Katzman film. Eva Bartók took her place.[15]
Writer Louis Pollock would be blacklisted for five years, having been confused for Los Angeles clothier, Louis Pollack, who refused to give testimony to the House Un-American Activities Committee.[16]
