The failure of the original copyright holder to renew the film's copyright resulted in it falling into public domain, meaning that virtually anyone could duplicate and sell a VHS/DVD copy of the film. Therefore, many of the versions of this film available on the market are either severely (and usually badly) edited and/or of extremely poor quality, having been duped from second- or third-generation (or more) copies of the film.
The ship shown at the pier John and Evelyn were going to at the end of the film was named the "Don Anselmo". It was originally named "Reeving Eye", a C1-M Alamosa-class cargo vessel, built for the U.S. War Shipping Administration by Kaiser Shipbuilding at Portland (OR) in 1945. It was sold to a Panamanian company in 1946. It sank off the coast of Peru in 1971 after a collision with an Ecuadorian Navy ship, with the loss of 13 lives.
According to the audio commentary by Imogen Sara Smith, production was shut down for a day and restarted after Steve Sekely was removed from the picture for creative differences, with Paul Henreid taking over. Sekely retained director credit for contractual reasons.
