The Phantom Stage?

Lon Chaney -- the Man of a Thousand Faces -- is eternally connected to one of his most famous performances, in more ways than one. Filming for his silent classic 'The Phantom of the Opera' took place on Soundstage 28 of Universal Studios, which has since been re-dubbed "the Phantom Stage." You can still find a piece of the Paris opera house set on the Phantom Stage after 80 plus years, and legend has it that you can also hear strange voices throughout. Crew members working on new projects have claimed to see a man in black resembling Chaney in his 'Phantom' garb roaming the catwalk.
