John Wells is no stranger to working with ensembles. An award-winning producer on a number of popular American TV shows – including E.R., The West Wing and Shameless – he made the jump to director with The Company Men (2010), a patient corporate drama headlined by Ben Affleck, Tommy Lee Jones and Chris Cooper.

For his sophomore directorial effort, Wells has taken on the ambitious task of adapting Tracy Letts’ Pulitzer Prize-winning play August: Osage County to the big screen. The film is chock full of A-List talent and impressive performances, and ahead of its UK release this week we got a chance to speak to him about working with so many talented actors, in addition to some of the challenges he faced.
