If you have already seen The Amazing Spider-Man 2, and stayed for the end credits scene, you would have seen this clip from X-Men: Days Of Future Past.
For those that didn’t catch the scene, the clip is now available to watch online!
If you are wondering why there was an X-Men scene in the end credits for a Spider-Man movie, director Marc Webb had an existing contract with Fox Searchlight to direct an upcoming movie and the only way that the studio would let him direct The Amazing Spider-Man 2 for Sony was to include the scene in the film for free, according to Variety.
