Starring a number of well-known young actors, including Downton Abbey’s Jessica Brown Findlay and The Hunger Games’ Douglas Booth, the film follows an elite group of students at Oxford University.

Desperate to join the infamous Riot Club - a more sinister version of The Bullingdon Club - two first year students Miles (Max Irons) and Alistair (Sam Claflin) are prepared to do whatever it takes to fit in.

But the initial banter of the Riot Club soon turns to something darker when the boys begin to vandalise university night spots and students’ rooms, before turning on themselves to attack each other.

Holliday Grainger (Jane Eyre, Anna Karenina) also stars as a grounded northern girl called Lauren, who tried to persuade Max Irons’ character Max to leave the club.

The film has been adapted for the screen by Wade and is directed by Lone Scherfig (An Education, One Day).

Wade’s sell-out play Posh premiered at the Royal Court Theatre in London in 2010, before transferring to the West End in 2012.

The Riot Club is due to be released on 19 September.
