Susan Boyle wants Julie Walters to play her in a film about her life.

The 'I Dreamed A Dream' singer - who shot to fame when she auditioned for UK TV show 'Britain's Got Talent' in 2009 - is in negotiations to turn her life story into a movie and is keen for the 'Harry Potter' actress to take the lead role.

Susan - whose story is already the subject of a stage show titled 'I Dreamed A Dream' - told the Sunday Mirror newspaper: ''My story will make a great film. We are in the middle of negotiations just now for a film about my life.

''There's only one person I'd love to play me - and that's Julie Walters. She would do the job and you just know she would do my story justice.''

The Susan Boyle film will follow another biopic of a 'Britain's Got Talent' star, Paul Potts.

James Corden is to play the car phone salesman-turned-opera singer - who won the show in 2007 - in 'One Chance', which is due out next year.
