Oct 27.-29,31

The Coolidge Corner Theatre lives for holidays like Halloween. The theatre doesn't need much of an excuse to go bananas for some off-the-wall festival or event, but Halloween is right in their wheelhouse. On Friday, the 2th, there's the midnight "Boy Band Sing-A-Long" meaning aging teens can along to tracks by the New Kids, N'Sync, the Backstreet Boys and more. But you'll get history, too: Programmer Henri of Austin's Alamo Drafhouse went back to the vaults for the Jackson 5 and Menudo, too. The next night, you do the same to "Hedwig & the Angry Inch" and they'll be giving a way a real piece of the Berlin Wall to the most Hedwigged out customer. Also on Saturday, the Halloween Marathon kicks up: 13 hours of terror and gore, running until noon Sunday. It starts with our call as the most realistic and frightening movie ever - Wes Craven's "Last House on the Left" - shot in cinema verite style and featuring the most realistic psycho killers the screen has seen. (Shot on a low budget, before Craven went mainstream.) Makes you gasp and squirm. Watch for what the killers make the trapped hippie girls do. Yeech! Watch how the revenge happens. Double yeech! Also: "Equinox," "Night of the Comet," "Vampire Circus," "The Gate" and "Near Dark." On Tuesday at 8 p.m. - the actual night of Halloween - it's time for the classic "Dr. Jekyl and Mr. Hyde" with the live score played by the Boston ensemble, Devil Music Ensemble.
