OFFER EXPIRED Be one of the first to see new film Carnage

Carnage is based on Yasmina Reza's stage play God of Carnage. Following a playground scuffle between their 11-year old children, the parents of the 'victim' have invited the parents of the 'bully' to their apartment to sort it out. Cordial banter gradually develops a razor-sharp edge as all four of the well-heeled American parents reveal their laughable contradictions and grotesque prejudices. None of them will escape the ensuing carnage in this hilarious new comedy. Extra members can see a preview screening of this film at selected cinemas on Sunday 22 January at 11am (see below for a full list of participating cinemas).
