Other mistake: In all of its appearances, the British flag (also known as the Union Flag and the flag of the United Kingdom) is wrong. The flag's X-shaped red Cross of Saint Patrick is shown as (a) wide, and (b) centered on its white background, whereas on the actual flag, it is (a) thin, and (b) not centered on its white background, but rather off-center in a counter-clockwise direction.

Directed by: John Huston
Starring: Humphrey Bogart, Katharine Hepburn, Robert Morley, Peter Bull
Continuity mistake: In the scene where there is a terrific storm while Bogart and Hepburn are asleep, Bogart gets extremely wet before being invited into the shelter by Hepburn. Upon entering the shelter and lying down to sleep, Bogart's blanket is perfectly dry.
Rose Sayer: Dear Lord, We've come to the end of our journey, and in a little while we'll stand before you. I pray for you to be merciful. Judge us not for our weaknesses, but for our love and open the doors of heaven for Charlie and me.
Trivia: Humphrey Bogart won his only Oscar for his performance as Charlie Allnut in this film.
