Elton John's biopic 'Rocketman' is already being turned into a stage show, despite the film, starring Tom Hardy, not even having been released yet.

The film - which will tell the story of the 68-year-old superstar's life and will include classic songs like 'Your Song' and 'I'm Still Standing' - will be moving to Broadway and then the West End with the help of the creative team behind the music adaptation of 'Billy Elliot', including its writer Lee Hall.

Producer Sally Greene, who runs London's Old Vic, told The Sun: ''It is in the works right now. It will be called 'Rocketman' but we will do the film first. It will open in Broadway before London.

''It will be Elton's back catalogue... he will never end his career.''

While Tom is starring as Elton - whose real name is Reginald Kenneth Dwight - in the film of the singer's life, it's unlikely he will be in the stage version, have previously revealed he struggled with the role, due to his lack of singing abilities.

The 'Mad Max: Fury Road' star said: ''I'm not a singer. I have no idea really. I'm really trying but it's hard to open my mouth in that way. I'm not really drawn towards singing and musicals and that stuff.''
