Creature of the Walking Dead is a 1965 American film adapted by Jerry Warren from the 1959 Mexican horror film "La Marca del Muerte". Warren's direct contributions to the film were extensive editing, minimalist dubbing of the Mexican players in select scenes, voice-over narration of the majority of Mexican footage, and the filming and inclusion of several brief scenes and shots made by Warren in the United States with American actors.

Dr. Malthus, a 19th-century mad scientist, discovers the secret of eternal youth by means of draining the blood of young women into his subjects. He is hung for his crimes, but his grandson inherits his home and revives him. Malthus then resumes his rejuvenation activities, enabled by the grandson.
