Marvel fans are growing concerned as reports emerge that Avengers: Doomsday is facing behind-the-scenes turmoil. Reported ego clashes between Robert Downey Jr. and the team have reportedly led to a feud on set, sparking worries among fans about the film’s overall production.

Many fans believe that Downey Jr. is feuding with Ryan Reynolds, known for playing the role of superhero Deadpool in the Marvel Cinematic Universe.
Not all’s well between Robert Downey Jr. and Ryan Reynolds
According to a report by Cosmic Book, Robert Downey Jr. has demanded reshoots. On the latest episode of The Hot Mic, Jeff Sneider claimed that Disney initially filmed three weeks of material with stand-ins for Downey Jr. inside the Doctor Doom suit, while the actor read lines off-camera.
“I’ve heard that even though they paid (Robert Downey Jr.) $50-60 million a movie, (Disney’s) had to reshoot for three weeks. They reshot three weeks worth of material because apparently–this is just what I heard–they had an actor standing-in for Downey Jr. In the (Doctor Doom) suit. They had a body double and they had a face double and Downey stood off-camera reading the lines, okay. And apparently, after two or three weeks, he was like ‘This isn’t working. I want to reshoot everything with me in the suit’,” Sneider claimed.
Sneider added, “The dysfunction I’ve heard on (the Doomsday) set is rivaled only by that of Fast and Furious movies. I mean, we’ve alluded to an incident BTS early this year that I did not want to go details on and it was probably more you know, someone made it sound more dramatic to me than it really was, but…yeah, I think again, there’s just a lot of testosterone and a lot of ego on that set. A lot of people who think they know what way is the best way. In the end, there’s only one person’s way who matters and that’s actually Robert Downey Jr.’s way.”
Fans are worried
While the actors’ names have not been confirmed, fans believe that Downey Jr. and Reynolds as the likely figures at the centre of the dispute.
One wrote, “Streets saying ryan reynolds and rdj fought on the doomsday set”, and another shared, “Well I’m sure that’s how the movie will go.”
One comment read, “Fortunately, I do like rdj! now with fandomwire adding fuel to the fire, I think the studio is working overtime to squash the fight.” “This could tank the film,” one fan shared.
Another fan shared, “Clashes happen when people care, if Ryan and RDJ really went at it, that just shows the passion behind the project. Energy like that usually makes the best scene.”
