It's no surprise that Twilight stars Kristen Stewart and Robert Pattinson are among Hollywood's biggest earners, alongside such mainstay stars as Robert Downey Jr. and Johnny Depp. See who else topped the Forbes list!
Forbes explains their numerology: "We used data gathered for our annual Celebrity 100 list to calculate each star's estimated earnings on each film (including up-front pay and any earnings from the movie's box-office receipts and first-year sales of DVDs). We then looked at each movie's estimated budget (not including marketing costs, which are susceptible to accounting chicanery) and box-office and DVD earnings to figure out an operating income for each film. We added up each star's compensation on his or her last three films and the operating income on those films, and divided the total operating income by the star's total compensation to come up with a return-on-investment number. The final number represents an average of how much a studio earns for every dollar paid."
