"I don't know if it's been announced. And I don't know how much ... Yeah, we're doing it next weekend," Feige said.
In a separate interview with Screen Rant, Feige said it won't be an extended cut, but rather "if you stay and watch the movie, after the credits, there'll be a deleted scene, a little tribute, and a few surprises."
Avengers: Endgame didn't include the traditional, post-credits scene -- only a short audio stinger of what sounds like clanking. Some internet theories suggest it's a nod to Iron Man.
"The Avengers assemble once more in order to undo Thanos' actions and restore order to the universe," reads a new listing from theater chain Cinemark. "Includes seven minutes of bonus content and Stan Lee tribute."
Marvel didn't immediately respond to a request for comment.
