The Russo brothers think Sony made a “tragic mistake” in ending their Spider-Man deal with Marvel. In early 2015, Marvel Studios and Sony Pictures reached an unprecedented agreement that allowed Spider-Man to be reinvented as part of the Marvel Cinematic Universe. Sadly, that deal has now ended, and the two studios have parted ways.
Directors Joe and Anthony Russo have been a part of the deal from the very beginning, when Marvel first approached Sony in the hope of incorporating Spider-Man into Captain America: Civil War. They knew how difficult it was to get two rival studios on the same page; as a result, the Russos have said they weren’t surprised Marvel and Sony parted ways, but avoided airing their opinions on the split.
