Many are predicting the return of the big movie musical. But there’s a hitch, writes Renee Graham. Where’s the talent to star in them? “Just a thought here, but isn’t the true magic of all that singing and dancing on film derived from having people who actually know how to sing and dance? Still, with the success of ‘Chicago,’ the first musical to win a best-picture Oscar since ‘Oliver!’ in 1968, just about every major studio is planning one, including possible remakes of ‘Jesus Christ Superstar,’ ‘Bye Bye Birdie,’ and ‘The Pajama Game.’ Unfortunately, there are way more musicals than viable musical stars these days.”
