When you head out to see “The Amazing Spider-Man 2” in theaters this May, stay after the movie for an end-credits scene. 

No, we’re not getting a tease of Spidey, Venom, or any of the web slinger’s Sinister Six crew.  

Instead, fans will see a montage for “X-Men: Days of Future Past” featuring Jennifer Lawrence’s character Mystique. 

This is confusing for fans who know that Sony Pictures distributes the Spider-Man films while Fox handles the X-Men franchise. 

What’s going on? Are Spider-Man and the X-Men teaming up in a future movie to take down Disney’s Marvel titan at theaters? 

Not yet, comic fans.

Variety reports the reason you’ll see the X-Men teased at the end of the film has to do with a deal between Sony and Fox because of “Amazing Spider-Man” director Marc Webb. 

From Variety: 

“Webb had an existing contract with Fox Searchlight to helm another film following 2009′s “500 (Days) of Summer.” After “The Amazing Spider-Man” in 2012, Webb’s negotiations briefly stalled with Sony as he was caught in a tug-of-war with Fox. Eventually, Fox agreed to allow Webb to direct Sony’s “Spider-Man” sequel, but only if Sony would promote its “X-Men” film for free.”

Yes, Sony agreed to run a promo for "Days of Future Past" after "Spider-Man."

The payoff is worth it for Sony. Since the sequel's debut overseas, it's already caused a lot of chatter online and end-credits scenes following Disney’s Marvel movies have helped draw interest and connect its wider Marvel universe.

The only problem is that viewers may be confused into believing there’s an X-Men / Spider-Man crossover in the works. 

“The Amazing Spider-Man 2” will be released May 2.
