Tom Hardy is singing ''all the time'' as he prepares to play Sir Elton.
The Dark Knight Rises actor will portray the pop legend in a new biopic, Rocketman, and he admits he has been taking extensive singing lessons to get ready for the film's numerous musical numbers.
Quizzed whether he's had vocal training, he said: ''Oh, all the time. I'm always singing.''
The star also revealed production on the film is still in the early stages but Elton, who is co-producing the feature through his Rocket Films production company, has been in touch.
Hardy explained to BANG Showbiz: ''It's all sort of under the radar at the moment, to be honest, but yes, I am talking to Elton.''
Rocketman, which is being directed by Michael Gracey, will tell the tunesmith's story from young child prodigy to musical icon.
Elton will re-record some of his classic songs for the fsoundtrack, but it's not yet known whether Tom's favourite song will make the cut.
He added: ''My favourite Elton song, I think it's Honky Cat.''
