Not by actual dollar value, but adjusted for inflation?

I've always been intrigued by this. Every summer there is a movie that becomes the highest grossing film of all-time. But it makes sense, because ticket prices go up every year, so the new movies will always out gross the classics.

I want real rankings!

Well, someone finally did the math, and we have a true number one.

Spoiler: Titanic is NOT #1.
