Eraserhead

Is it a nightmare or an actual view of a post-apocalyptic world? Set in an industrial town in which giant machines are constantly working, spewing smoke, and making noise that is inescapable, Henry Spencer lives in a building that, like all the others, appears to be abandoned. The lights flicker on and off, he has bowls of water in his dresser drawers, and for his only diversion he watches and listens to the Lady in the Radiator sing about finding happiness in heaven. Henry has a girlfriend, Mary X, who has frequent spastic fits. Mary gives birth to Henry's child, a frightening looking mutant, which leads to the injection of all sorts of sexual imagery into the depressive and chaotic mix.

Eraserhead is a surrealist-horror film written and directed by David Lynch, and released in 1977. In 1971, Lynch moved to Los Angeles to pursue an MFA (Masters of Fine Arts) degree at the AFI Conservatory. At the Conservatory, Lynch began working on his first feature-length film, Eraserhead, using a $10,000 grant from the AFI. The grant was not sufficient to complete the film and, as a result, Lynch worked on Eraserhead intermittently until its release in 1977. Lynch used money from friends and family, including boyhood friend Jack Fisk, a production designer and the husband of actress Sissy Spacek, and from odd jobs to finish the film.
