Built in the 19th century, right in the middle of Harvard Square, the Brattle looks more like a barn than a movie theatre. A non-profit that’s dangled close to the edge of bankruptcy several times, the historic single-screen carries on, marching to the beat of its own eclectic programming. The decor isn’t fancy, but the schedule generally has something worth seeing, from Twin Peaks episodes to yearly Valentine’s Day screenings of Casablanca. With classic films, cartoon marathons, new documentaries, rare Japanese horror, best-of-the-year recaps and staff picks all on the roster, it’s good for open minds and omnivorous tastes. More easygoing than the nearby HFA, the Brattle serves beer and also hosts book events and live music on occasion. Showtimes can be a little erratic, so it’s best to double-check the website.
