Disney did not immediately respond to requests for comment. Specifics about how much new footage will be in the film that already runs three hours is unclear.

"Not an extended cut, but there will be a version going into theaters with a bit of a marketing push with a few new things at the end of the movie," Feige told ScreenRant. "If you stay and watch the movie, after the credits, there'll be a deleted scene, a little tribute and a few surprises."

Feige said that the rerelease will hit theaters next weekend. It's unclear how many screens it will play on and how long the rerelease will be in theaters.

The Disney film already broke numerous box office records in its original release, becoming the second-highest-grossing film of all time, behind James Cameron's Avatar. Endgame is still in 1,420 theaters — a large number for a film that was released nearly two months ago.

Endgame destroyed records in its $1.2 billion worldwide launch. It was an unheard-of opening that came in nearly $600 million ahead of the mark set a year ago by Avengers: Infinity War.

It is the record holder for biggest opening in North America with $350 million. Infinity War was the previous record holder at $257.6 million, followed by Star Wars: The Force Awakens at $248 million.

Endgame has made $2.74 billion to date. Avatar, also released into theaters multiple times, made $2.8 billion.
