so is it a sequel ?
i know that mario bava is in the same league of de palma , argento , carpenter ,whaller etc .. i haven't seen any movies to him but since am a big fan of the other mentioned directors i decided to get to know the guy..i decided to start with schock ... but is it a sequel ? .. why would a legandary director do a sequel not something entirely his ? ... or is it called beyond the door II js for advertising ? ..
