The Riot Club is set to be autumn's hottest film. Starring some of Britain's most exciting rising talent (Max Irons, we're looking at you), it's based on Laura Wade's play, Posh, about a group of elitist and misogynistic students at Oxford University.

Playing the two central female characters is Holliday Grainger (The Borgias) and Jessica Brown-Findlay (Downton Abbey).

Both characters in the film have to deal with some very upsetting behaviour from the boys in The Riot Club, so we caught up with them to talk testorone-fuelled film sets, not being one of the boys and dealing with those difficult scenes.
