The Mummy Bust (1932)

Boris Karloff as The Mummy, a 1932 Universal release.

From Wikipedia:

An Ancient Egyptian priest called Imhotep (Boris Karloff) is revived when an archaeological expedition led by Sir Joseph Whemple (Arthur Byron) finds Imhotep’s mummy. Despite the warning of his friend Dr. Muller (Edward Van Sloan), Sir Joseph’s assistant Ralph Norton (Bramwell Fletcher), recklessly reads aloud an ancient life-giving spell. Imhotep escapes from the archaeologists, taking the Scroll of Thoth, and prowls Cairo seeking the reincarnation of the soul of his ancient lover, Princess Ankh-es-en-amon.
