In February, it was announced that Spider-Man will finally be rejoining his Marvel family in the movies. You see, years before Marvel got into the movie-making business, they licensed Spider-Man to Sony Pictures, which prevented Spidey from joining the party after Marvel started making their own blockbusters. The major announcement came with the confirmation from Marvel that  Spider-Man will be appearing in an unnamed Marvel movie next that will take place within the Marvel Cinematic Universe.

And thanks to this new leak... we might know what that movie is. Though its authenticity hasn't been confirmed (why would it be?), the end credits from the upcoming Avengers: Age of Ultron have leaked via YouTube—and it contains a huge, huge surprise. Watch below...... and, of course, just in case it wasn't already clear: Here's your spoiler warning. 

Avengers: Age of Ultron will be in theaters May 1 in North America. Two sequels, Avengers: Infinity War Part 1 and Avengers: Infinity War Part 2, are scheduled for May 2018 and May 2019 releases, respectively.
