John Huston's 1951 adaptation of C.S. Forester's story about a prim but determined missionary (Katharine Hepburn) and a crass but heroic riverboat captain (Humphrey Bogart) journeying down the Congo in a tiny boat in order to sink a German vessel at the start of World War I is great fun ... for the audience, anyway. Those working on the film with Huston had a bit less fun, as fictionalized in screenwriter Peter Viertel's novel White Hunter Black Heart, which Clint Eastwood turned into a movie. Put all that out of your mind and enjoy one of the wittiest and most charming adventures in film, with great one-liners ("Nature, Mr. Allnut, is what we are put in this world to rise above"), cinematography and fantastic chemistry between Bogart and Hepburn. If only this hadn't inspired dozens of inferior rip-offs, though I did enjoy the episode of Muppet Babies that paid homage to it.
