Ever thought of what’s the deal with Spider-Man? X-Men? Why are they not in these films? It just seems wrong, they were not in the movie .
The reason is because different studios hold the rights. That’s actually the main reason you saw the New Spider-Man film so soon after Spider-Man 3. If they didn’t use it, they’d lose it. It’s also why Blade and Ghost Rider have reverted back to marvel recently, and why Daredevil and Elektra did the same last year. Turns out you’re more likely to see those come into the Avengers-Sphere than Spider-Man, Fantastic Four or X-Men. Although, I would love it, the respective makers have said as much too, but they know it wouldn’t happen.
