After reports of a supposed feud between Robert Downey Jr. and Ryan Reynolds were debunked, a new rumor claims the real confrontation on the Avengers: Doomsday set involved two Thunderbolts actors instead.
Wyatt Russell and David Harbour Named
According to YouTuber Doomcock, sources say the altercation was between Wyatt Russell, who plays John Walker/US Agent, and David Harbour, who plays Red Guardian.
The situation reportedly happened during filming for a Thunderbolts segment of the movie:
âIt was not as bad as it seems. We do have names now, and it seems the altercation was between Wyatt Russell and the guy that plays the Red Guardian, David Harbour. As Iâve said, it was mostly a shouting match between the two and a shove. And thatâs about all that happened.â
The incident is described as a shouting match that escalated into a shove. The source claims it started after Russell complained about a part of his role being cut, and Harbour made a remark he didnât appreciate:
âAllegedly, it was over Wyatt getting a part cut, and he was complaining about it, and the Red Guardian said something that Wyatt didnât like.â
Reportedly Resolved
While the clash raised eyebrows and went viral online, Doomcockâs sources downplayed the severity, saying the issue has been smoothed over and tensions have since cooled. The two actors are said to have moved on, with no lasting fallout from the confrontation:
âWyatt Russell, if you recall, plays John Walker, aka US agent. So, apparently, this was during a Thunderbolt segment of the movie that this happened.â
âFrom what Iâm hearing, things are smoothed over now between the two. So, no harm, no foul.â
Doomsdayâs Growing Reputation
The story adds to a string of rumors about on-set problems for Avengers: Doomsday. Even if this dust-up between Russell and Harbour was minor, it continues to paint a picture of a production full of pressure and personality clashes.
New rumors offer that Robert Downey Jr. is threatening to quit unless the script gets fixed.
