Awfully tired Abbott and Costello comedy, their 28th (and final) film for Universal, benefits from a good supporting cast--although the script is cluttered with villains who don't end up doing much. Two pith helmet-wearing Americans in Cairo get hold of a medallion which points the way to hidden treasure once owned by a princess (but in hieroglyphics!). Soon, they're on the run from the mercenary Madame Rontru and her stooges, plus three roaming mummies guarding the princess's tomb. Lots of frantic activity, but not enough jokes. As the nefarious Madame, Marie Windsor gives the proceedings a much-needed shot in the arm, however Bud and Lou phone their performances in. *1/2 from ****
