LONDON: Paul McCartney is writing his first stage musical, an adaptation of the classic movie 'It's a Wonderful Life.' The ex-Beatle is collaborating with 'Billy Elliot' playwright Lee Hall and West End producer Bill Kenwright. McCartney said he'd never considered writing a musical, but after meeting Kenwright and Hall three years ago, 'found myself thinking this could be interesting and fun.' Hall said McCartney's 'wit, emotional honesty and melodic brilliance brings a whole new depth and breadth to the classic tale.' Frank Capra's 1946 film tells the story of George Bailey, a small-town banker wracked with regret who is shown the value of his life by a guardian angel. Producers said Thursday they are aiming for a late 2020 launch for the show. Its dates and venue have not been released.
