Just as Avengers: Endgame was drifting from theaters to Blu-Ray, the movie is being re-released with some extra footage. Marvel Studios president Kevin Feige revealed the news at a press junket for Spider-Man: Far From Home.
Feige said, "We are doing that. I don't know if it's been announced. And I don't know how much... Yeah, we're doing it next weekend."
Feige also told ScreenRant that the new version is"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. If you stay and watch the movie, after the credits, there’ll be a deleted scene, a little tribute, and a few surprises.”
Endgame is trying to beat Avatar and be the highest-grossing movie ever and TBH I'm not mad at it.
