Nestled beneath the luminous beacon of its old-timey marquee, the Clinton Street Theater cements its status as Portland’s oldest continuously running independent film house with a rotating slate of foreign films, documentaries, and cult classics. Weekly screenings of The Rocky Horror Picture Show and Repo: The Genetic Opera draw fervent cultists dressed as their favorite characters and boom-mic operators, complementing screenings of splattery horror flicks with thought-provoking opera from rising and renowned auteurs. The cylindrical glow from a whirring projector jets across the Clinton’s spacious theater, illumining arrivals from such directors as Sidney Lumet and Gus Van Sant, who is notorious for instructing his actors to break character midfilm to challenge texting film-goers to bare-knuckle brawls.
