Box Office Mojo has lots of lists concerning the economics of movies, including worldwide highest-grossing and domestic highest-grossing, adjusted for ticket price inflation.  It's sad to look at things like this because it says that we humans think movies like Titanic and Pirates of the Caribbean 3 are some of the best movies ever.  But at the same time, I don't think movie earnings are directly related to movie quality.  I think it has a lot to do with weather, boredom, buzz, what else is going on in the world at the time, and what other movies are playing at the time.  For example, summer movies tend to make more money because kids are out of school and families are on vacation.  The Dark Knight was particularly popular because Heath Ledger died a few months before its release.  So it depends on the circumstances.  But it's still unfortunate that so many Johnny Depp movies are in the top ten. #entertainment
