And circling back to that unfortunately cancelled X-Men Vs Fantastic Four project that was in early consideration in 2010, there would have been an even bigger movie event on the back of it: Secret Invasion.
After the fighting had come to an end between the superheroes and the superhero registration act was presumably no more, they would have had an almighty stinger in the shape of a Skrull invasion in the post-credits to be concerned about.
Now, obviously we got to see a Skrull invasion storyline in Captain Marvel, but Marvel Studios chose to subvert expectations and robbed comic book fans of a pure adaptation that had the potential to be truly brilliant. And to think we could have had an alternate version that would have included the Fantastic Four, X-Men, Deadpool and Daredevil sounds like a missed opportunity of some scale.
