Twilight stars Kristen Stewart and Robert Pattinson and Alice in Wonderland's Anne Hathaway are topping the Forbes' new "Hollywood's Best Actors for the Buck" rankings.

The Forbes has calculated the estimated earnings of each star from its Celebrity 100 list, including upfront salaries, backend points and DVD sales from their last three movies in the past five years, relative to those flicks' box office returns, in order to determine an average of how much a studio earned for every dollar paid.

The survey counted films that opened in more than 500 theaters, excluding animated pictures (for which the actors who contributed voice work aren't considered the draw).

21-year-old Kristen Stewart, most widely known for her role as Bella Swan in Twilight topped the ranking with an average return on investment of USD 55.83, i.e. for every $1 the actress was paid, her films tallied $55.83.

She was followed in second place by Anne Hathaway, who averaged USD 45.67 and proved the exception to the franchise rule.

Her number was largely based off roles in one-off hits including Tim Burton's Alice in Wonderland,  which grossed over USD 1 B worldwide, and Valentine's Day, which netted USD 216 M globally.

Despite playing opposite Stewart in Twilight, Robert Pattinson came in third with an average BFTB of USD 39.43 due to the middling returns of Remember Me and Water for Elephants.

Daniel Radcliffe took the fourth spot with USD 34.24 for Harry Potter's spectacular box-office run; the Transformers trilogy's Shia LaBeouf rounded things out in fifth place with USD 29.40 even though Transformers: Dark of the Moon wasn't counted, as Forbes only tabulated movies released before May 1, 2011.
