Take a crash course in B-movie horror to prepare for this Halloween. For the tenth year running, American Cinematheque will host a nightlong marathon of seven '80s movies played back-to-back, ranging from campy guilty pleasures to iconic favorites. This year's lineup consists of Halloween III: Season of the Witch, Death Spa, Anguish, Spookies, Dead and Buried, Pieces and The Nest. The way-reasonable price ($20 for 6 movies?) even includes all-night snacks and coffee so you won't doze off.
