The Warner Beverly Hills is featured in the low budget film "Blood Theatre" (1984). Starring Mary Woronov. The film (also known as "Movie House Massacre") is presented in Blood-O-Rama.
The Warner, once a grand first run venue, had become an independent 99 cent theatre by the time of the filming. And was demolished about six years later for a parking lot. See our page on the art deco style Warner Beverly Hills, once called "The Pride of Beverly Hills." Well, it called itself that -- on the side of the building.
