On this chart, films are ranked by the revenues from theatrical exhibition at their nominal value, along with the highest positions they attained. Five films in total have grossed in excess of $2 billion worldwide, with "Avatar" ranked in the top position. All of the films have had a theatrical run (including re-releases) in the 21st century, and films that have not played during this period do not appear on the chart because of ticket-price inflation, population size and ticket purchasing trends not being considered.
