"Lux Radio Theater" broadcast a 60 minute radio adaptation of the movie onJune 10, 1940 with Merle Oberon and Pat O'Brien reprising their film roles.

Although the character's name has changed, Frank McHugh plays the same part as he had in the original version titled "One Way Passage."

Geraldine Fitzgerald was pregnant with her son Michael Lindsay-Hogg during the filming, which is why she has so many close-ups in the beginning but seems to disappear in the second half of the movie.

Illness caused director Edmund Goulding to be replaced for much of the film. Anatole Litvak shot approximately 26% of the film, William Keighley 4%, and 'Howard, William K. (I)' shot a few retakes. Goulding shot 70% of the picture around bouts of pneumonia.

Pregnancy caused Geraldine Fitzgerald to miss several shooting days. A double was used where possible.

Remade as a segment of The Love Boat, with John Forsythe and Ursula Andress in the lead roles. This was part of the two-hour season-opening special "The China Cruise" (7.1, 1 October 1983).
