Welsh star Catherine Zeta-Jones is married to actor Michael Douglas

Catherine Zeta-Jones is rumoured to be in talks to play Susan Boyle on the big screen.
 
The actress, 39, and director James Cameron are said to be interested in securing the film rights to the Britain's Got Talent's life story.

'All these people are coming out and want to be associated with her,' a source tells the Daily Mail. 'She is the biggest thing in the world. It is mental.'

Katie Holmes, 30, has also expressed her support for Susan, 48.

‘I think she's great,’ she tells The Sun. ‘I think whatever she wants to do, she can do.’

Catherine’s US publicist denies she has plans to play the singer.

Meanwhile, Susan has rubbished reports she'll quit Britain's Got Talent because she can’t handle the media attention.
