Scarlett Johansson had to reject the lead role in an Andrew Lloyd Webber’s musical because of her hectic schedule. The musical mogul was sad after the actress’ declension to star in his hit musical adaptation of 'The Sound of Music'. Weber thinks Scarlett, who trained the tunes for hours to play Maria, is a ‘natural star.’ He told UK magazine Heat, "She certainly has the voice to do it. She's terrific, a natural star for musicals."
