Joe Russo is definitely not mad at Martin Scorsese
Joe Russo made a cute little joke about owning the box office that reignited the Marvel vs. Martin Scorsese feud

There is no opting out of Martin Scorsese vs. The Marvel Cinematic Universe: every time the conversation seems to have subsided, the debate flares up again with some new provocation. That’s partially because interviewers can’t stop asking the director to reiterate his opinions on the subject, and partially because those involved with the MCU can’t stop responding defensively to those opinions. The latter is also largely prompted by interview questions, but every once in a while a Marvel guy will blurt out some Scorsese nonsense unprompted, and the result is… whatever Joe Russo has going on in this video.
Here’s the story: Scorsese and his daughter have been posting some adorable TikToks during the press run for Killers Of The Flower Moon, including one where he comically tries to direct his dog, Oscar. Avengers: Endgame co-director Joe Russo “stitched” the video from his production company AGBO’s account, joking, “Aw look, he’s got a schnauzer! I love schnauzers. And his name is Oscar. That’s really cute.” The camera then zooms out to Joe holding his own dog, to whom he says, “Okay, come on, Box Office.” (“It appears we share the same muse,” they captioned the post on Instagram.)
