The battle between Marvel and Martin Scorsese fans has reached a fever pitch.

The Killers of the Flower Moon director famously said in 2019 that superhero movies are not cinema. After being slammed on social media by ardent Marvel fans for his opinion, he can now add Avengers director Joe Russo to his list of apparent critics.

Russo, who co-directed Infinity War (2018) and Endgame (2019), the two highest-grossing Avengers films , posted a video Friday on Instagram to boast about his success and mock Scorseses accomplishments.

Aw look, hes got a schnauzer! I love schnauzers. And his name is Oscar. Thats really cute, said Russo in the video following spliced-in footage of Scorsese with his dog, the aptly named Oscar, before Russo addressed his own dog. OK, come on, Box Office.

Russo, who has 2.9 million Instagram followers, received 35,000 likes for the post.

This entire discourse was spawned from a mere opinion Scorsese shared in 2019, when he told Empire magazine of Marvel films : I dont see them. I tried, you know? But thats not cinema.

The closest I can think of them, as well made as they are, with actors doing the best they can under the circumstances, is theme parks, he added. It isnt the cinema of human beings trying to convey emotional, psychological experiences to another human being.
