Dana Andrews wore opaque contact lenses throughout filming to give him a realistic sensation of blindness.
This film bombed at the box office, resulting in a loss to RKO of $1,040,000 according to studio records.
RKO initially sent a second unit to record a concert at Carnegie Hall in New York City, but moving the sound equipment in and out of the venue proved to be too difficult, so a replica set of the hall was constructed at the studio instead.
The beach scene was filmed at Trancas Beach, California, not far from where the final scene of The Planet of the Apes (1968) was filmed.
Dana Andrews and Hoagy Carmichael shared scenes in The Best Years of Our Lives one year earlier.
