Epsilon’s CV spans from Shakespeare to new writing featuring, Time Out Critics Choice Extremities by William Mastrosime, Fun Like Stalingrad by Len Pentin & a sell out production of Othello .

We strive to produce theatre of the highest caliber. We aim to tell good stories simply and well, making points to which each member of the audience can relate. One of the driving forces behind Epsilon is to be able to give unknown talent, on both sides of the footlights a platform to hone their skills and excel. We are passionate to find pieces of theatre that stand out from the crowd that hits the solar plexus of the audience and takes them on a roller coaster journey of emotion. We look to fire debate in the bar during the interval and to stand as a talking point amongst friends.
