The theatre has been home to the musical theatre version of "The Lion King" since 1999. To celebrate the 10th anniversary of the production, which had grossed over £289 million and been seen by more than eight million people, 250 former cast members gathered onstage, together with designer-director Julie Taymor. James Earl Jones, who voiced the role of King Mufasa in the original Disney animated film, attended the performance. During a halt in performances and closure of the theatre, due to the COVID-19 pandemic, the theatre flooded on 11 May 2020.
