Spider-Man has teamed up with the X-Men countless times in the comics and video games and on Saturday morning television. Yet the odds of the two Marvel Comics properties uniting on the silver screen has long seemed unlikely due to different movie studios owning their rights and being heavily reticent to crossovers.

In a somewhat unprecedented move, however, it’s been revealed that The Amazing Spider-Man 2 will feature as its post-credits highlight a special preview of X-Men: Days of Future Past.
