Only five movies have ever crossed $2 billion at the box office, without adjusting for inflation.
Using Box Office Mojo, Insider compiled the only films to cross the threshold.
"Avatar," which is getting a long-awaited sequel in December, is still the highest-grossing movie.
5. "Avengers: Infinity War" (2018)

The traumatic cliffhanger at the end of "Infinity War" was a must-see, movie-going moment for fans. No one was expecting the film to end on such a grim note with Thanos (Josh Brolin) not only defeating the Avengers, but snapping away half of all life from existence.
In 48 days, the film crossed $2 billion worldwide.
