Johnny Depp has been voted the world's most bankable film star in 2007, according to a survey of movie exhibitors. The annual survey by Quigley Publishing Co. asked theatre companies to vote for the 10 stars who generate the most cash for them. And Depp came up on top thanks to Pirates of the Caribbean: At World's End and Sweeney Todd: The Demon Barber of Fleet Street. Will Smith came second, followed by George Clooney, Matt Damon, Denzel Washington, Russell Crowe, Tom Cruise, Nicolas Cage, Will Ferrell and Tom Hanks. No actress has made the top 10 in the last 24 years.
