The global box office has a new king in 'Avengers: Endgame.'

The superhero extravaganza this weekend usurped “Avatar” to become the highest-grossing film of all time, with an estimated $2.79 billion in worldwide grosses in just 13 weeks.

'Avatar' held onto the record for a decade at $2.789 billion.

The title comes with a few caveats, however, including the fact that “Avatar’s” grosses are not adjusted for inflation. Also, domestically, 'Avengers: Endgame' is No. 2 to 'Star Wars: The Force Awakens' by around $80 million.

Marvel Studios president Kevin Feige gave a shout-out to 'Avatar' director James Cameron Saturday night at San Diego Comic-Con for holding the record for so long. Feige also noted the inflation technicality and said Cameron will probably hold the title again someday.
