Stage manager Maurice Cass vows that the opera will go on "even if Frankenstein walks in!" Audiences were well aware that this in-joke referred to star Boris Karloff, who was in the theater at the time.
The red cape used by Boris Karloff in this film was sold on December 16, 2011 for $19,000.00 + 4,370.00 buyer's premium + 8.25% sales taxes + shipping and quite possibly other added fees. A display mannequin made to Karloff's Gravelle character effigy came with the cape.
This film was first telecast in Detroit Monday 14 September 1953 on WXYZ (Channel 7), in New York City Monday 11 January 1954 on WCBS (Channel 2), in Los Angeles Friday 23 April 1954 on KNBH (Channel 4), and in San Francisco Wednesday 20 April 1955 on KRON (Channel 4).
