Alexander Hanson, recently on the West End stage in An Ideal Husband opposite wife Samantha Bond, is to play Simon Cowell in The X Factor musical after impressing the casting team and Cowell himself in auditions.
The 51-year-old actor - whose TV work includes roles in The Bill, Casualty and Auf Wiedersehen Pet - apparently had Cowelll "howling with laughter" as he looked on during the read through.
A source told The Sun: "He's not exactly a Hollywood A-lister but he does a bloody good Simon Cowell. Simon had to admit he was the right man for the job."
In the production, Hanson's Cowell sings a huge number called Falling In Love With Myself - a send up of the X Factor judge's vanity.
The comedy-musical has been written by former TV Burp star Harry Hill, while Steve Brown - who was responsible for much of the music in satirical puppet programme Spitting Image - has written the songs.
The storyline follows the journey of pop hopeful Shenise - believed to be loosely based on real life winners Alexandra Burke and Leona Lewis - who goes on a journey from a caravan park caring for her father, who has an iron lung, to win the singing competition.
The judging panel is made up of a Geordie - based on ex-judge Cheryl Cole - a Louis Walsh-type character and Cowell, who, at the end of the musical, is revealed to be an alien in control of planet earth.
Cowell's record label, SyCo, has funded the £10 million production - set to run at the London Palladium next spring - and even though the show mocks his talent show, he is said to be delighted with the end result.
A source close to the star said: "He genuinely loves it. Simon knows that many people see him as a bit of a cartoon character so he doesn't mind being made fun of.
"It's a very funny script Harry Hill has put together and the songs are laugh-out-loud amusing."
