Shia LaBeouf offers most bang for the buck

He tops the list of actors who offer the best investment return for a Hollywood film, according to Forbes. For every dollar that's paid to LaBeouf, the films he appears in generate an average of $81 in profits. It doesn't exactly hurt that LaBeouf starred in the first "Transformers" blockbuster (Paramount got him for under $5 million).

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. Most of that payback is coming from Alice in Wonderland. The Disney 3-D film was a gigantic hit earning $1 billion at the global box office, and Hathaway earned much less than star Johnny Depp. But she also benefits from 2009's Bride Wars, which was a modest hit earning $115 million at the global box office on a low estimated budget of $30 million.
