Comic actor Will Ferrell has the dubious distinction of heading a new Forbes magazine list of Hollywood's most overpaid stars. A top-ten list also includes (in order) Ewan McGregor, Billy Bob Thornton, Eddie Murphy, Ice Cube, Tom Cruise, Drew Barrymore, Leonardo Dicaprio, Samuel Jackson, and Jim Carrey. All of them, said the magazine on its website Wednesday, "cost more to hire than they appear to be worth at box offices." Ferrell ended up at the top of the list, it said, largely because of the flop Land of the Lost , a movie that cost about $100 million to produce, but which earned less than $65 million worldwide. Based on his estimated salary for each film, Forbes concluded that for every dollar Ferrell was paid, his films earned an average of just $3.29.
