On An Average Day is the first play by the young writer John Kolvenbach to be seen in London. Kolvenbach's previous work has been produced in New York, Chicago and Toronto. The play is set in rural upstate New York. 'Jack' (Kyle MacLachlan) unexpectedly returns home after a fifteen-year absence to find his abandoned younger brother, 'Robert' (Woody Harrelson), living in a private world that is far from ordinary.
Robert is on trial for a bizarre traffic incident, is hoarding a shower full of newspaper clippings and has something unsavoury living in the fridge. And what has Jack been hiding from Robert all these years? Painfully funny and genuinely moving, the story reveals that on an average day extraordinary things can happen.
