Fans at last saw Spider-Man introduced into the Marvel Cinematic Universe with Captain America: Civil War, but it will be a long, long time before they witness the X-Men do the same. Until then, they can watch this epic fan trailer, which pits Marvel's mutants against Earth's Mightiest Heroes, over and over and over again.

Seriously, Fox and Marvel aren't going to reach any kind of deal in the foreseeable future, so settle in with this video on a loop.

It's produced by mashup veteran Alex Luthor, who's demonstrated time and again his ability to weave engaging new narratives from existing footage. Here, he pulls footage from films ranging from X-Men to Avengers: Age of Ultron to Deadpool to tease a franchise-shaking showdown that depicts and all-out war between mutants and humanity, with the two teams at the center of the action.
