What was the First ever Hollywood Mummy movie?

The first ever Hollywood mummy movie is generally considered to be "The Mummy" (1932), directed by Karl Freund and starring Boris Karloff.

While there were earlier films featuring mummies, such as "The Mummy's Hand" (1922), they were either silent films or were not produced in Hollywood.

"The Mummy" (1932) was a major success and established the mummy as a popular horror icon in Hollywood cinema. It also helped launch Boris Karloff's career as a horror film star.
