"Beware of the Blob!" One of the great cult classics, The Blob melds '50s schlock sci-fi and teen delinquency pics even as it transcends these genres with strong performances and ingenious special effects. Made outside of Hollywood by a maverick film distributor, a crew experienced in religious and educational shorts, and a collection of theatrical talent from Philadelphia and New York, The Blob helped launch the careers of superstud Steve McQueen and composer Burt Bacharach.
