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 29th, there's the midnight "Boy Band Sing-A-Long" meaning aging teens can sing 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 hors of terror and gore, running until noon Sunday. It starts with our call as 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. Makes you gasp and squirm. 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.
