Reshoots are typical on any superhero movie, but the “Avengers 4” reshoots are apparently very necessary. Star Mark Ruffalo hinted that the new scenes could change parts of the story.

During The Marvelists: The MCU Podcast, the Hulk actor revealed that he is going back to shoot additional scenes this month. Ruffalo explained that though the film technically wrapped last year, they didn’t really get to complete it.

“We don’t even know what [‘Avengers 4’] is going to be yet,” Ruffalo admitted. “We’re not just doing reshoots. We’re going to finish the movie, which we really didn’t get to finish totally when we left it last year.”

He added that changes are constantly made, even as filming is happening. He questioned if even the writers and directors know the “Avengers 4” story.

“I don’t even know that they really know exactly,” Ruffalo said. “Some of it is happening while we’re there. It’s pretty amazing. And we’ll shoot some stuff and a few days later come back and reshoot it cause we want to take it in another direction. So it’s a very living organism, even as we approach it being a locked picture, we’re still working on it.”

The directors and writers likely have a good idea of where the story is going, but they probably aren't telling Ruffalo. After all, he totally spoiled “Avengers: Infinity War.”

However, his revelation about changes happening while they’re on set has fans wondering. What could that other direction be? It’s hard to say since “Avengers 4” spoilers are being kept secret, but many viewers are speculating that some of the reshoots could involve the Guardians of the Galaxy.

With the third film on hold indefinitely, the reshoots could give their storyline a more concrete ending. There are also rumors that some of those characters could be killed off. Dave Bautista, who plays Drax, has made it clear that he doesn’t really want to return after Disney fired director James Gunn. He also hinted that characters’ fates could change in the “Avengers 4” reshoots.

“It’s on permanent hold for now, and that may make a difference in what they do with our characters in ‘Avengers 4.’ To be honest with you, right now I really don’t know,” Bautista told Digital Spy. “But I know I’m in ‘Avengers 4.’ I’ve shot most of it already. I do have two days of reshoots. But other than that, I have some really great scenes that I hope they use. But I guess that it remains to be seen what they’ll do with the characters.”

Marvel, of course, has not confirmed anything about the Guardians of the Galaxy and their fates in “Avengers 4.” Fans will have to wait until the movie premieres on May 3, 2019, to see what happens to all those who were affected by Thanos’ snap.
