Sir Elton John would like to see Robert Downey Jr. play him in the planned film about his life.

The 'Rocket Man' singer has already announced there is a film based on his life planned, and that he is teaming up with British screenwriter Lee Hall on the project, and although it is in its early stages at present, Elton already has one actor in mind to portray him.

Speaking at the London premiere of 'Gnomeo And Juliet', Elton, 63, joked to BANG Showbiz: "A biopic of my life? I'm quite old now so they'd have to be two or three actors and they'd have to vary in weight. Robert Downey Jr. could maybe play me at a certain stage."

The singer has previously worked with Robert when played the lead role in the star's video for his track 'I Want Love' in 2001.

Although details of the film are quite scarce, Elton - who is married to David Furnish - has said it will not be a straight biopic, and would like to give and more take a more "surrealistic" version of his life.

He said: "Obviously, it's not going to be your normal, run of the mill film because my life has kind of been crazy. And I think it's important to do a kind of surrealistic take on my life."

Elton has also said he expects the project to take around two years to complete.
