Which 1931 film features Boris Karloff as Frankenstein’s monster?

The 1931 film featuring Boris Karloff as Frankenstein’s monster is Frankenstein.

Directed by James Whale, the film follows Henry Frankenstein, a scientist who assembles a living being from human body parts. Karloff’s performance, assisted by Jack Pierce’s makeup design, established the monster’s flat-topped head, neck bolts, and heavy boots as enduring screen images.

The film was produced by Universal Pictures and adapted from Peggy Webling’s stage version, which itself drew on Mary Shelley’s 1818 novel. Colin Clive played Henry Frankenstein, while Mae Clarke played Elizabeth. The monster is often called “Frankenstein,” but Frankenstein is the scientist’s surname; the created being is generally referred to as Frankenstein’s monster. Universal later connected the character with other classic monsters in crossover films.
