In an interesting twist, Sony Pictures and 20th Century Fox are working together to cross promote their upcoming Marvel movies, with The Amazing Spider-Man 2 featuring a post-credits action sequence from X-Men: Days of Future Past that is exclusive to the sequel's release in theaters.
While Post-Credits sequences have become expected as of late, The Amazing Spider-Man 2 decided to forgo any type of tease in setting up The Amazing Spider-Man 3. Its unclear if early fan outrage at this spurred the unique merging of these two Marvel films, but now, U.K. residents can see the sequence when the movie opens in theaters today, and U.S. audiences can see it when the film opens in the states on May 2nd.
The sequence does not tie the two films together in any way. It's merely a 'reward' for those who decide to stay seated throughout the credits. Empire first reported on the news, giving this brief description of what audiences can expect to see.
Empire speculates that this promotional team-up between the studios may lead to something bigger and better down the road, maybe an end credits stinger that finds Spider-Man and any one of the X-Men sharing the same screen, something fans have been clamoring for. This isn't the first time two studios have tried to merge their franchises. There was early talk to include a shot of the OsCorp building in the New York skyline of Marvel's The Avengers, which didn't pan out. This new agreement between Sony and Fox is one step closer to seeing the Marvel worlds merge on screen.
