John A. Marta, a veteran cinematographer, and Aaron Stell, a long-time film editor, also worked on the film. Marta had shot close to 150 B movies for Republic Pictures by this time, which is probably why he was hired (given AB-PT's relationship with that studio and Marta's fast-and-quick shooting style). Albert Glasser composed the musical score. Glasser worked in the same office building where Gordon had his offices, and Gordon admired his score for the 1956 war film "Huk!" (a B movie from Pan Pacific Productions). Gordon had already used Glasser to score his 1957 monster movie "The Cyclops". Glasser wrote the musical score for "Beginning of the End" as well as five more of Gordon's films. Glasser was paid $4,000 for his work on "The Cyclops", which may indicate how much he was paid for the musical score for "Beginning of the End". The musical soundtrack included the song "Natural, Natural Baby." The art director was Walter Keller.
