 Concept art revealed in June 2016 showed the inclusion of an opening montage of Spider-Man going up against C and D-list villains, such as Mysterio, the Shocker, the Prowler, and the Rhino, with the Vulture serving as the main antagonist.As disagreements between Sony and Raimi threatened to push the film off the intended May 6, 2011 release date, Sony Pictures announced in January 2010 that plans for "Spider-Man 4" had been cancelled due to Raimi's withdrawal from the project.Raimi reportedly ended his participation due to his doubt that he could meet the planned May 6, 2011 release date while at the same time upholding the film creatively; he admitted that he was "very unhappy" with the way "Spider-Man 3" had turned out, and was under pressure to make the fourth film the best that he could.
