"A dream of dark and troubling things": this is the entire synopsis of Eraserhead provided by Lynch, master of understatement. Eraserhead is the story of Henry, cursed with an innocence bordering on retardation, and a lonely life in the box-like apartment he shares with his radiator. Henry, however, does have a girlfriend, and she is in a family way through means which neither can fathom; the scene in which he must propose marriage is possibly the most pregnant moment in film history. Their life together is filled with substance--every rubbery, liquidy, textured, nauseating substance one could imagine--and Baby makes just one more, a genuine horror that only a parent could love. Eraserhead is not for the squeamish, precisely because every image (and sound) evoked in this ingenious film is somehow all-too familiar. It is, on the other hand, a treat for anyone who has had inexplicably equivocal feelings about Los Angeles, where it was filmed at night.
