In the 1931 classic "Frankenstein", the monster does what to Maria after playing with her?

In the 1931 classic "Frankenstein," the Monster tosses Maria into a lake after playing with her. Maria has been gathering flowers beside the water and invites the childlike Monster to play by throwing them into the lake.

When the flowers run out, the Monster assumes Maria will float like them and throws her into the water. She drowns, although the Monster does not appear to understand that he has killed her. The scene emphasizes his frightening strength and limited grasp of human consequences.

The sequence is based on an episode from Mary Shelley's 1818 novel, in which the Creature encounters a young girl. It was controversial during the film's release: some censors demanded that the drowning be cut, and the footage was later restored. A common mix-up is calling the character Frankenstein; Frankenstein is the scientist, while the unnamed Creature is played by Boris Karloff.
