Trivia

To make the mummy appear more frightening, Tom Tyler's eyes (and the inside of his mouth) were blacked out frame-by-frame in almost all close-ups.

Several shots and sequences in this film (including the scene where Kharis is punished by being buried alive) are lifted directly from Universal's 1932 original version of "The Mummy", the studio's philosophy being: "Why re-stage and re-shoot something we've already got in the can?"

For the scenes in which the Mummy was seen in closeup or medium shots, Jack P. Pierce's painstaking makeup technique of gluing strips of cotton on Tom Tyler's face, to create deep wrinkles, was employed. But in long shots, Tyler wears a time-saving (and much more comfortable) rubber mask.

The large impressive tomb set was originally built for Universal's "Green Hell" and appeared again in other Universal features.

Dick Foran's character here of an adventurous archeologist fascinated with ancient artifacts served as partial inspiration for the later creation of Indiana Jones.
