Win Min Than's husband was so jealous about losing her to the film's "decadent" Hollywood star Gregory Peck, he ordered his wife to eat garlic before romantic scenes with Peck. Fortunately, the production crew was able to convince her husband that Peck and the others were respectful of her so he went home leaving her to finish the picture in peace.
An article in the 14 March 1954 edition of the New York Times noted that the Royal Air Force provided three de Havilland Mosquito bombers and all the required crew from Singapore. The bomber used for the crash scene was shipped from the U.K., stripped of its engines, and cost the production company all of $35.
Just before the crash, Peck's navigator references "Where the dawn comes up like thunder". This is a quote from "Mandalay" by Rudyard Kipling.
Blore's quote, "Theirs not to reason why...", is from "The Charge of the Light Brigade" by Alfred Lord Tennyson.
