The Bush, which for more than 40 years has created a formidable output from new writers, started as a pub theater and in 2011, thanks to a lifesaving campaign that rallied support from the likes of Judi Dench and Daniel Radcliffe, got its own facility in a disused Victorian library. Besides attracting exciting writers, it brings in stars (like Kate Beckinsale and Alan Rickman) who want to connect with audiences.
