Debuting in July of 1983, the dancing zombies of this movie predate the Michael Jackson: Thriller (1983) release by about four months.
The film's closing credits declare that this picture was: ''Filmed on location in Oregon, Los Angeles, California, New York City and at the Warner Hollywood Studios in Hollywood''.
The name of the institution was the ''Hellview Home for the Terminally Strange''.
The movie was made in the mould of the then recent smash box-office comedy Y a-t-il un pilote dans l'avion ? (1980) and was anticipated as being a horror genre version of it. Notable is that the film actually first released in the same 1982 year as the movie's sequel [See: Y a-t-il enfin un pilote dans l'avion ? 2 (1982)].
