Wasn't Avatar the first $2 billion film, on its initial release?
I think they were talking about this year's movies.
Is there a list of movies that broke 2B since Avatar?
The only other movie to break to the 2 billion mark was Titanic and that was after it's 3D release. But it is amazing that three movie so far this year has broken the 1 billion mark and I suspect that Spectre, The Force Awakens and Mockingjay part II will join them.
