6 of 10: For every dollar Robert Downey Jr. is paid, his films earn an average $18.74, says Forbes, which places the 'Sherlock Holmes' and 'Iron Man' actor on the sixth spot on its 2011 list of Best Actors For The Buck.

In 2010, Downey Jr. appeared in films such as 'Iron Man 2,' which made about $623 million worldwide, and reluctantly embarked on a crazy road trip with Zach Galifianakis in the comedy 'Due Date,' which garnered about $211 million.

'Sherlock Holmes: A Game of Shadows' sees Downey Jr. reprising his title role from a 2009 hit film and hits theaters on Dec. 16, 2011. He also re-suits up as the superhero Iron Man in 'The Avengers,' set to be released in May of 2012, and in 'Iron Man 3,' due out in 2013.
