On the surface, The Phantom of Hollywood, a TV movie from 1974, may seem like it’d only appeal to the most devoted of B-horror aficionados. A retelling of The Phantom of the Opera, the film has plenty of inventive killings and questionable dialogue to satisfy those viewers, but it also holds value for fans of classic films—particularly those interested in MGM. That’s because The Phantom of Hollywood was actually filmed on the MGM backlot as it was being parceled off and torn down. The movie makes great use of that decaying, yet familiar, setting, and also creates a fun, rebellious, pro-film anti-hero as its villain.
