To celebrate its 15th anniversary, Northwest Film Forum is screening 15 titles it’s helped birth. Beginning the “Arboring Film” series tonight, appropriately, is NWFF co-founder Jamie Hook’s 2003 screwball comedy The Naked Proof. In it, a grad student (Michael Chick) is blocked on his long-gestating philosophy dissertation; he’s visited by a mercurial pregnant woman (the wonderful Arlette Del Toro), who may or may not be a symbol of his epistemological disgruntlement. Preceded by local shorts, other screenings will include Greg Lachow’s Money Buys Happiness (Sun.), Lynn Shelton’s We Go Way Back (Thurs.), and Guy Maddin’s Brand Upon the Brain! (also Thurs.). A concluding party on Friday, Oct. 1 simultaneously launches the Local Sightings film festival, which runs the following week. (NR) BRIAN MILLER
