Hollywood's Best Paid Actors

LOS ANGELES -- Earning $20 million upfront for a movie is so 2007. These days studios are squeezing every cent they can out of actors, and that means many stars only earn the big bucks after the studio gets back its money.

In these frugal times it's useful to look at which actors earn studios the most for their money. Pay someone $10 million to star in your big summer blockbuster and what can you expect for your investment? If you hire Shia LaBeouf, expect a lot. For the second year in a row, he tops our list of Hollywood's Best Actors for the Buck.

When LaBeouf starred in the first Transformers movie in 2007, Viacom's ( VIA - news - people ) Paramount Studio was able to pay him under $5 million. It had to bump that up considerably for the second film (which earned $833 million in 2009), but LaBeouf still isn't earning $20 million upfront to star in a picture.

As a result, he offers a great return on investment. For every $1 studios spend on the 24-year-old actor his films return an average $81 of profit. For our list this year LaBeouf also benefits from the fourth Indiana Jones film, which earned $790 million in 2008. George Lucas, Steven Spielberg and Harrison Ford split the bulk of the profits from that movie leaving LaBeouf as a profitable costar.

As the actor's fame (and box-office earnings) increase he'll be able to demand more for each film which will hurt his return on investment number unless the films are gigantic blockbusters. That could be the case with the next Transformers movie. LaBeouf was able to ask for more money upfront but because the movie is being filmed in 3-D, it should earn even more than Transformers 2.

In order to create our list we looked at the top 36 earners in Hollywood. To qualify, each actor had to have starred in at least three movies in the past five years that opened in more than 500 theaters. Movies that opened after June 1 of this year are not counted. We did not include animated films because the actors aren't really the draw and they tend to take pay cuts for voice work.

We then used data gathered for our annual Celebrity 100 list to calculate each star's estimated earnings on each film (including upfront pay and any earnings from the movie's box-office receipts, DVD and TV sales). We then looked at each movie's estimated budget (not including marketing costs, which are susceptible to accounting chicanery) and box-office, DVD and television 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 total operating income by the star's total compensation to come up with each return on investment number. The final number represents an average of how much a studio earns for every dollar paid to the actor.

Because women typically earn less than men in Hollywood, they make up a full half of our top 10 list. Anne Hathaway is the highest-ranking woman in the No. 2 spot. For every dollar she earns studios earn $64 off of her films.
