Major new musical Opening Night, based on the legendary John Cassavetes film, is having its world premiere in the West End. It follows a theatre company as it prepares to stage a new play on Broadway but backstage drama ensues when the production’s leading lady is hit by tragedy, which forces everyone to deliver the performance of their lives. And there are some big hitters involved – Tony and Olivier Award winner Ivo van Hove is directing, Rufus Wainwright is behind the music and lyrics, and BAFTA and Olivier Award winner Sheridan Smith is starring.
