User blog comment:Mark4518/X-Men’ Producer Would Love An ‘Avengers’ Movie Crossover/@comment-1895174-20130219133851/@comment-3317214-20130219222301

I'm not saying we should necessarily have the characters appear in crossover films, other than just cameos in eachother's. The films can pretty much stay fairly separate as they are now, but acknowledge eachother's existence, and they would be in a cohesive universe, and it would be awesome. But anyway, didn't Stan Lee create Spider-Man, X-Men, Fantastic Four, Iron Man, Hulk, Thor, Ant-Man and Wasp, Nick Fury, Doctor Strange, and the Avengers over the span of just 3 years?
