Originally filmed in the late 1960s as Psycho a Go-Go (1965), a crime drama about a jewel robbery gone wrong, it sat on the shelf for two years before new footage incorporating the zombie plot were shot by investors who wanted a less serious horror film.

Tommy Kirk stated in a 1993 Filmfax interview that he was paid $1,000 for two days' work. The film was non-SAG and co-star Kent Taylor was subsequently disqualified from the SAG for doing non-SAG films for money.
