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.
