"Beware of the Blob!"

(aka 'The Glob" or"The Molten Meteorite" or "The Meteorite Monster" or "The Glob That Girdled the Globe" or "The Night of the Creeping Dead')

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
