Abbott and Costello Meet the Mummy is a 1955 comedy horror film directed by Charles Lamont and starring the comedy team of Abbott and Costello. It is also the 28th and final Abbott and Costello film produced by UniversalInternational.
Abbott and Costello go to the doctors house to apply for the position to accompany the mummy back to America. However, two of Semus men, Iben Mel Welles and Hetsut Richard Karlan, murder the doctor and steal the mummy just before Abbott and Costello arrive. The medallion has been left behind, though, and is found by Abbott and Costello, who attempt to sell it. Rontru offers them 100, but Abbott suspects it is worth much more and asks for 5,000, which Rontru agrees to pay. She tells them to meet her at the Cairo Caf, where Abbott and Costello learn from a waiter that the medallion is cursed. They frantically try to give it to one another the Slipping the Mickey routine from The Naughty Nineties, until it winds up in Costellos hamburger and he swallows it. Rontru arrives and drags them to a doctors office to get a look at the medallion under a fluoroscope. However, she cannot read the medallions inscribed instructions, which are in hieroglyphics. Semu arrives, claiming to be an archaeologist, and offers to guide them all to the tomb. Meanwhile, Semus followers have returned life to Klaris.They arrive at the tomb, where Costello learns of Semus plans to murder them all. Rontru captures Semu, and one of her men, Charlie Michael Ansara, disguises himself as a mummy and enters the temple. Abbott follows suit by disguising himself as a mummy, and he and Costello rescue Semu. Eventually all three mummies are in the same place at the same time, and the dynamite that Rontru intends to use to dig up the treasure detonates, killing Klaris and revealing the treasure. Abbott and Costello convince Semu to turn the temple into a nightclub to preserve the legend of Klaris and the three criminals who wanted to steal the treasure are presumably arrested. ........
