In the last few years, Nicole Kidman has starred in a number of movies that underperformed at the box office, but last year's disappointing grosses for The Interpreter The Invasion, The Golden Compass and even Margot at the Wedding likely contributed to her being named the least bankable actor in Hollywood by Forbes magazine. Apparently, given her exorbitant asking price, Forbes estimates her movies only earn, on average, as much from ticket sales as she earns for appearing in them. This is a major drop compared to last year, when Kidman's films were estimated to gross $8 for every $1 she's paid.

After Kidman, Forbes names Jennifer Garner, whose '07 films The Kingdom and Catch and Release did poorly enough that the runaway success of Juno couldn't help her ranking. On average her films grossed $3.60 for every $1 she took home. In third place, not surprisingly, is Kidman's ex, Tom Cruise, who bombed big time with Lions for Lambs last year. Others making the list of most overpaid actors include Nicolas Cage, Drew Barrymore, Cameron Diaz, Jim Carrey, Cate Blanchett and Will Ferrell. Meanwhile, Russell Crowe, who topped the list last year, is considered more fairly paid this year thanks to the success of American Gangster.

Such fluctuations in actors' bankability only continues the debate regarding the importance of movie stars these days. Certainly all the names on Forbes' list are big names who occasionally headline blockbuster hits, but are they actually significant to moviegoers' attraction to a movie? Apparently not.

So, which actor do you think is most in need of a major reality check before his or her next major paycheck?
