1. "Avatar" (2009)

Total gross revenue: $2,788,000,000

James Cameron's "Avatar" is also sitting pretty as the highest-grossing movie of all time. With more than $2.7 billion in box office revenue, it's miles ahead of other films on the list. But as ticket prices increase and billion-dollar movies become more common, we'll have to wait and see how many more years "Avatar" can claim the No. 1 spot.
