Low CinemaThe Low Cinema, a new single-screen movie theater in Ridgewood that opened in May, is a nostalgic trigger for millennial New Yorkers of a certain vintage. The team behind the Rockaway Film Festival—which, for the last seven years, has held outdoor screenings in the Rockaway neighborhood of Queens—is working toward establishing a full-time, year-round cinematheque. In contrast, the uptown Metro Theater was once a single-screen movie house with an Art Deco facade and 550 seats. That’s the kind of optimism fueling the Rockaway Film Festival, which will host its eighth edition later this summer. Like Low Cinema, the Arverne Cinema is a labor of love.
