Ewan McGregor is to make his West End musical debut in a new production of 'Guys and Dolls'.

McGregor will play the lead role of chronic gambler Sky Masterson in the production, which opens in the late spring of next year.

The Artistic Director of the Donmar Warehouse, Michael Grandage, will direct the production; McGregor agreed to star when Grandage agreed to reschedule the musical to accommodate the actor's filming commitments.

McGregor last appeared on stage in 1999 in a production of 'Little Malcolm and His Struggle Against the Eunuchs' at London's Comedy Theatre.
