101 Films presents Children Shouldn’t Play with Dead Things, Bob Clark’s first step into Horror. With almost no budget and a cast and crew made up of friends, Clark triumphs with an eerie, funny and genuinely terrifying Zombie classic with an excellent turn by frequent collaborator Alan Ormsby as the dreaded director ‘Alan’.

Led by a mean-spirited director, a theatre troupe travels by boat to a small island for buried criminals. The group gets more than they bargained for when the dead rise from their graves. Can they stay put until daylight against the undead onslaught, or do they flee into the pitch-black night? Will anyone survive?
