This lovely, melancholy documentary is about Danny Williams, a filmmaker and lighting designer at Andy Warhol's Factory who—sometime after being discarded by his shock-haired impresario of a lover—drove his mother's car to the shore, walked into the water, and never came back. Tonight, Northwest Film Forum will also screen four of Williams's 16mm films and host a question-and-answer session with Esther Robinson, a documentarian and Williams's niece. (NWFF, 1515 12th Ave, 267-5380. Documentary 7 and 9:15 pm, $8.50; Factory films 8 pm, $15.)
