The Mummy (1932)

The Mummy, although It reveals that master of makeup Karloff in the weirdest of his movie disguises to date, is somewhat less horrifying than Frankenstein and less skilfully produced than Dracula, which it seems to resemble in its general design.

[Director Karl Freund] employs some good moving camera tricks and presents tremendously effective full-sized close ups of Boris Karloff.

Karloff makes a wonderful creation from this strange sort. [Full review in Spanish]

The Mummy owes a great deal to Willy Pogany, artist, illustrator, and mural painter, who designed its sets.

As in Frankenstein, Karloff's ability to communicate through his makeup is vital to establishing his character, even in human form, it's clearly pain and not incarnate evil that dictates his actions.
