The African Queen, (1951) Bogart, Hepburn and the odd crocodile or two

Despite the corny opening for this trailer, this movie is, to my mind, one of the best romances ever filmed--outstanding performances by two actors in their prime. Some of the picture was shot in Uganda by director John Huston and the company. It was not an easy film to make. Months were spent in a jungle encampment. The "African Queen" boat used in the film sank at least once (shades of "Jaws" and the mechanical shark). Leeches and fire ants plagued the crew and everyone got sick except Humphrey Bogart, who reportedly warded off tropical maladies by drinking copious amounts of hard booze.
John Huston "prepared" for the picture in part by going on elephants hunts, in one case almost losing Katherine Hepburn--who was armed with a camera--during an unexpected pachyderm stampede in high brush.
Part of the real-life background for the film was later made into a under seen film directed by and starring Clint Eastwood and Marisa Berenson, called "White Hunter, Black Heart" (1988), from a novel by Peter Vietrel. Vietrel worked with Huston as a screenwriter on the earlier film and the main character--a reckless American film director--was based on Huston himself. Huston apparently didn't mind being caricatured and mentioned the book favorably in his own autobiography.
In the later film, Eastwood essentially played John Huston, accent and all.
Hepburn wrote a fine memoir about her experiences on the film, Bogart won an Oscar, and the movie itself ends happily on a wild twist of fate that was in stark contrast to Huston's usual fatalistic outlook in films like "The Treasure of the Sierra Madre" (1948), "The Man Who Wold Be King" (1975) and "The Asphalt Jungle" (1950).
