The world premiere in Atlanta, GA, was attended by the members of the 501st Parachute Battalion who worked on the production.
According to the February 12, 1941 Los Angeles Times, Lucille Ball was being considered. The role eventually went to Nancy Kelly, who was married to star Edmond O'Brien on February 19, 1941, doubtless influencing RKO's casting decision.
Towards the end, the aircraft in which the two parachutists try to catch up with the rest of the battalion (in DC-2s), and which looks like a pregnant Harvard, is a North American O-10 observation aircraft.
Patric Knowles and Charles Quigley were listed in early production charts as actors, but were not seen in the film. Also, Eddie Gribbon is in studio records playing a bartender but was likewise not seen in the film.
