The Mainstage at Riverside Studios is a 400-seat theatre in West London. In recent years, it has been home to Ulster American (starring Woody Harrelson & Andy Serkis), Second Best (starring Asa Butterfield), and Operation Mincemeat, among others.
Mainstage Season Artistic Director Andy Sandberg said today, ‘New writing has always been my passion, and there is nothing more exciting than discovering and nurturing a brilliant original play. Our hope is that each of these stories will resonate with audiences and become part of the theatrical canon for years to come. These are all timely and thought-provoking scripts designed to entertain while also inviting audiences to engage more deeply. I absolutely love working in the UK, and I am honoured to be working alongside a brilliant team of UK colleagues to bring this season to life. The experiences I have had directing in London have been some of the most gratifying of my career, and I can’t wait to launch these new productions at Riverside Studios.’
The Mainstage Season at Riverside Studios is presented by ABS Productions, Whitney Edwards, Flora Major, Judith Manocherian, Sondra Biller, and Berman-Cohen Productions. DEM Productions serves as General Manager.
