Written by Mills and Henry Fitzherbert, the film's cast features Asa Butterfield, Finn Cole, Hermione Corfield, Michael Sheen, with Nick Frost and Simon Pegg.

After his father dies, Donald Wallace (Finn Cole), a teenager from a working-class family, enrolls in an exclusive public school called Slaughterhouse, where he struggles to fit in.

The school houses a few secrets, such as the recent suicide of a pupil last term, mysterious disappearances, an overzealous house prefect who descends from a long line of war criminals, and an enigmatic new sinkhole, caused by the Headmaster's (Michael Sheen) money-making scheme: fracking.

The website's critics consensus reads: "An uneven blend of horror and comedy that fails to satisfy on either front, Slaughterhouse Rulez aims for B-movie fun but doesn't make the grade.
