Dorothy Pomerantz took a look at which stars bring in the most box-office revenue for every dollar they are paid. Highlights of the article include:

• Natalie Portman is at the top of the list. For every dollar she is paid, her movies return $42.70.
• Eddie Murphy, on the other hand, is the most overpaid star. For every dollar he earns, his films only make $2.30.
• Portman’s success is, in part, due to Black Swan, which had a very small budget, but did incredibly well at the Box Office.
• Kristen Stewart has the distinction of being both among the highest paid actors in Hollywood and one of the best investments.
• In fact, all of the main stars of the Twilight series make it onto the list of most profitable actors.
• Daniel Radcliffe, the star of Harry Potter, also makes the list although he is expected to drop off it as the franchise has come to an end.
