Kristen Stewart, Shia LaBeouf Named Top Box Office Performers

Call them gorgeous and perhaps overpaid, but let's not forget that at the end of the day, actors are still employees. And some certainly perform better than others.

While many a movie star is remembered for being "box office poison," failing to earn a studio or production company their salaries back in box office sales, the folks at Forbes have compiled a list of celebs who consistently produce gold.

Oscar winner Natalie Portman tops the list, returning an average of $42.70 for every $1 she's paid. Credit the phenomenon of 2011's awards hit "Black Swan," made for just $13 million and earning $329 million in domestic and international sales.

That's a lot of tutus.

The list was calculated using Forbes' Celebrity 100 index and receipts from Box Office Mojo over the last three films from a given star – like "Twilight Saga" queen Kristen Stewart, who clocked in at number two.

Stewart brings in a reported $40.60 for every $1 placed in her Balenciaga wallet, thanks to the juggernaut conclusions to the vampire franchise "Breaking Dawn" parts 1 and 2.
Stewart also performed an impressive feat in launching "Snow White and the Huntsman," co-starring Chris Hemsworth and Charlize Theron. She's already confirmed for a sequel.

Though former "Transformers" headliner Shia LaBeouf rounds out the top three, Forbes makes an interesting note about his earning potential in lists to come.

The actor, who rates $35.80 on the dollar, has been more than vocal about his desire to step away from blockbuster films like Michael Bay's explosive fare and move into a more independent genre – not your typical lucrative popcorn flick.

Other bold-named boys who appear on the list include Robert Pattinson (#4) and Daniel Radcliffe (#5).
