The box office has been very kind to Natalie Portman and Kristen Stewart over the last few years.
Thanks to stellar returns on films like "The Black Swan" and "Twilight: Breaking Dawn," both leading ladies have topped Forbes [4] magazine's list of Hollywood's most bankable stars.
After considering the actors' earnings, along with their last three major movies' box-office receipts and budgets, Portman was determined to be the most valuable player in the industry.

"Black Swan," Darren Aronofsky's ballet thriller that earned Portman her first Oscar, only cost $13 million, but it went on to gross $329 million worldwide. Her "No Strings Attached," a $25 million rom-com co-starring Ashton Kutcher, raked in $150 million worldwide.
Though her other comedic venture, "Your Highness," failed to recoup its $50 million budget, Forbes estimates studios earned $42.70 for every buck they paid Portman.
In the case of Stewart, it's pretty easy to see why she came in second: "The Twilight Saga" has brought in $3.3 billion (and counting).

The last two installments alone have made over $1.5 billion worldwide, a figure that easily repaid her massive $25 million paycheck. Franchise co-stars Robert Pattinson and Taylor Lautner also placed on the Forbes list, but they didn't star in "Snow White and the Huntsman" -- a $396 million hit for Universal.
All considered, Stewart earned studios $40.60 for every dollar she was paid.
