In First Man Into Space, exposure to cosmic rays transforms a test pilot into a murderous monster! Marshall Thompson and Marla Landi struggle to find and save him. A dubious premise that might have been redeemed by more compassion for the victim. John C. Cooper and Lance Z. Hargreaves wrote the screenplay. Directed by Robert Day. Produced by John Croydon and Charles F. Vetter, Jr. Click for other version of poster
