The 1930s saw the rebirth of horror movies with the advent of sound films. Sound added tension through music, footsteps, and other audio cues. Universal Pictures launched a successful horror film series including Tod Browning's Dracula (1931) and James Whale's Frankenstein (1931), which blended Gothic horror and science fiction. These films featured iconic monsters created by makeup artist Jack Pierce and starred actors like Boris Karloff and Bela Lugosi who built careers in the genre. Frankenstein contained controversial scenes that were cut for its original release involving the monster drowning a girl and Frankenstein's line "Now I know what it feels like to be God!"
