When The Amazing Spider-Man 2 became a legitimate movie-going experience this week in the UK, fans who stuck around for the end credits found themselves staring at something they never quite expected. During the final credits scene, then, movie-goers were treated to a (spoiler warning, people) clip from the upcoming X-Men: Days of Future Past, which featured Jennifer Lawrence's Mystique breaking into a military base in the 1970s. This, of course, got everyone thinking things like: "OMG! Is Spider-Man gonna team up with the X-Men or something?" Well, no, unfortunately not. Despite the fact that the producers opted to include a little teaser for Days for Future Past at the end of The Amazing Spider-Man 2, no such superhero team-up is going to happen. Firstly, these movies aren't even set in the same world, let alone the same year (Spider-Man is set in the present, whereas Days of Future Past takes place mostly in the '70s). Secondly, the rights to these characters are owned by two very separate studios - Sony have their mitts around Spider-Man, whereas 20th Century Fox have ownership over the X-Men. So why, and how, did this oddity occur? Basically, it came about due to a contractual obligation: Marc Webb, who made (500) Days of Summer for 20th Century Fox and directed both The Amazing Spider-Man and The Amazing Spider-Man 2, still owes them another movie. But when Sony decided that they wanted the director to start work on the sequel to The Amazing Spider-Man 2 straight after the first, the studios made a deal: Sony could keep Webb for the next movie, just as long as they opted to include a teaser for Days of Future Past in the end credits. Weird, huh? Anyway, no team up is happening, nor will it at any point soon. So everyone get just get on with their lives, we guess. Bah. What do you make of this?
