While it wasn’t on the London premiere, you may have heard that there is a new comic book themed post-credit teaser at the end of ‘The Amazing Spider-Man 2‘. While that shouldn’t be too surprising as Marvel has been doing that in their films for years, what is surprising is that the post credit footage is for the upcoming movie ‘X-Men: Days of Future Past‘. For those of you who don’t follow movie rights, the X-Men are owned by Fox while Spider-Man is owned by Sony. This kind of a cross studio advertisement is quite unexpected. Could this be a sign that we’ll be seeing a Spider-Man crossover in an upcoming ‘X-Men’ or ‘Fantastic Four’ movie? Not quite.

Actually there is a rather entertaining reason for the mutant piece appearing in a Spider-Man film. Apparently ‘The Amazing Spider-Man 2’ director Marc Webb still owed Fox a movie after 2009′s ‘500 (Days) of Summer’. However, filming a movie would have interrupted the timeline to do the sequel to  ‘The Amazing Spider-Man’ movie. The solution? Fox would allow Webb to direct the next installment on everyone’s favorite webhead on the promise that they would get some free promotion for the next ‘X-Men’ film. As neither the ‘Venom’ or ‘Sinister Six’ films will be coming out until after ‘The Amazing Spider-Man 3’, it didn’t seen to be that much of a stretch to push this through.

In the montage itself we see  Mystique (Jennifer Lawrence) along side Havok (Lucas Till) and Toad (Evan Jonigkeit) fighting off a military force that is run by  William Stryker (Josh Helman_. While it is cool to get that kind of an early premiere, it is cited that this is an actual scene from the movie which isn’t quite as fun as how Marvel does post-credit scenes specifically filmed to be a teaser.

I don’t know about you but with no promise of a crossover or a shared universe this really doesn’t do much for me. What are your thoughts on two rival companies using one another without any direct payoff to the fans? Share your thoughts below!

‘The Amazing Spider-Man 2′ hits theaters on May 2, 2014. Andrew Garfield is back as Peter Parker, along with Emma Stone as Gwen Stacy. Jamie Foxx as Max Dillon/Electro, along with Dane DeHann as Harry Osborn. The film also features Sally Field and Chris Cooper.
