Actress Bess Armstrong once said of her co-star Tom Selleck whilst doing publicity for the picture: "He is real gorgeous, and he has some real power now, but he doesn't use that, or his charm, to exploit women. He genuinely seems to like women. For an actor, that's rare".
Actors Tom Selleck and Bess Armstrong had to overcome a significant height difference between them whilst blocking their scenes together. Armstrong is quoted in the January 1984 edition of Photoplay (UK) magazine as saying: "I spent five months in four-inch heels and standing on soap boxes just to reach him".
Bess Armstrong once said of the very low temperatures during the movie's production shoot: "...I found Yugoslavia so cold they had to pin layers of thermal under my flapper dress in such a way it wouldn't show...it made it impossible for me to go to the bathroom without six helpers and two people on walkie-talkies relating my progress to the director, the cameraman and anybody who happened to be standing around!".
The make and models of the three bi-planes in the film were all vintage Belgian-designed French-built Stampe SV4C aircraft that were built after World War II though in the film the planes portray World War I era bi-planes.
