Common Sense Note
Parents need to know that this WWI romantic comedy-adventure has a troubling threat of death-by-execution for the main characters. There is light violence in the form of gunfire and dangerous river rapids. Squeamish moments involve blood-sucking leeches and, to a lesser extent, a painful mosquito swarm. As with most old-school movies set in Africa, black natives are unimportant compared to the white-European folk -- but at least they aren't treated with contempt or mockery.
Very mild suggestion that Charlie and Rose sleep together. Rose seems to be naked when bathing in the river (but actually she's covered with a slip).
A hail of gunfire. German soldiers bully people (one dies offscreen) and burn a grass-hut village. A threatened execution by hanging. Icky scene of Charlie plagued by blood-sucking leeches. Talk of torpedoes and bomb-building.
Love-story message of a greatest possible "opposites attract" variety, with staid, spinsterish Rose falling in love with ill-mannered, hard-drinking Charlie, and the two learning to appreciate and respect each other. Secondary theme about striving against near-impossible odds to fight tyrannical enemies.
A novel of the same name by C.S. Forester exists but has been completely overshadowed by the movie adaptation.
Drugs / Tobacco /
Charlie smokes cigars and drinks gin, finally to the point of drunkenness. Rose disapproves of alcohol, sending his stash into the river.
