Cinematographer Jacques R. Marquette and his Marquette Productions made this film because they needed a very inexpensive feature to fill out the bottom of a double-feature package with their previously produced The Brain from Planet Arous (1957). Marquette kept production costs as low as possible by shooting the picture himself and hiring an inexpensive director. However, the day before principal photography was to begin, the director quit the production, claiming that he had been offered a 14-week contract by a major studio. Marquette had no time--or money--to hire another director, so he took over the job himself, making this his only film as director, and gave the job of cinematographer to a new cameraman whose first job this was.
A scene from this movie is shown in Once Upon A Time In Hollywood, which has to do with Charles Manson's followers. In the scene shown, a woman is telling the wolf boy, "I love you, Charles."
This was shot under the title "Meteor Monster" but the title was changed to "Teenage Monster" due to the success of monster movies from other distributors which has the word "teenage" in the title. When it was released to U.S. television, the title was changed back to "Meteor Monster" for the 16mm television syndication prints.
The film was originally refused a UK certificate in 1959 (as "Teenage Monster"). It was eventually released in 1995 fully uncut with a PG certificate.
The first day's shooting was "day for night". Because the new director of photography was inexperienced in shooting day for night,the entire day's shooting had to be scrapped because the camera negative was so underexposed that an acceptable image could not be printed from it.
