It was announced in February 2019 that Ball will star as Inspector Javert opposite Alfie Boe (Jean Valjean) in a staged concert production of Les Misérables. The production will open on 10 August 2019, at the Gielgud Theatre and serve as a placeholder while the original West End production of Les Mis at the Queen's Theater is replaced with Cameron Mackintosh's new staging of the show at the renamed Sondheim theatre. The staged concert was broadcast live to cinemas in the UK on 2 December 2019, and then encore showings in the UK and the USA. This staged concert has become the highest live stream concert at cinemas in UK history.
