A hole was made in the ceiling of Carnegie Hall to accommodate sound and lighting equipment for the filming in 1946 and remained there until renovations were done in the 1990's.
Before filming began, workmen cleaned and redecorated Carnegie Hall so that it would appear as new for the scenes set in 1891 when it first opened, according to an article in the October 5, 1946 edition of Cue magazine.
According to an article in the April 3, 1944 edition of The Hollywood Reporter, this film was planned to be shot in Technicolor, star Ronald Colman and have a budget of $1.8M.
