Bud Abbott and Lou Costello temporarily leave their usual Universal stamping grounds to star in the Huntington Hartford production Africa Screams. Costello plays the colorfully inept Stanley Livingstone, a meek book salesman who poses as a big-game hunter at the behest of his shifty pal Buzz Johnson (Abbott). It's all part of a scheme to extract some money from adventuress Diana Emerson (Hillary Brooke), who intends to search for a lost diamond mine in the heart of Africa. It seems that Stanley has committed to memory a long out-of-print book which contained a map to the mine. Despite his mortal fear of wild animals, Stanley accompanies Buzz, Diana, and Diana's henchmen on the African expedition. The subsequent comic complications involve a legendary giant gorilla, a cannibal tribe, and a friendly orangutan who falls in love with Stanley. Animal trainer Clyde Beatty and big-game tracker Frank Buck make cameo appearances while character comics Shemp Howard and Joe Besser provide laughs as, respectively, a nearsighted gunman and a sissified flunky. Also on hand are boxer brothers Max Baer and Buddy Baer, who engage in an amusingly unconvincing display of fisticuffs. But the film belongs to Abbott & Costello, who are in fine form.
