A week ago, a video surfaced online of what appeared to be an Avengers: Age Of Ultron post-credits scene feauring our first look at Marvel's Spider-Man. It had the whole internet debating whether it was real or not and even Joss Whedon had to publicly announce that it was fake at an Avengers 2 press conference.
Now you can watch a behind-the-scenes video from the pranksters themselves, which details how much effort they put into one of the greatest pranks of all-time.
The prank was directed by Chris White and Larry White. Spider-Man was played by Paolo Paz aka South Beach Spidey and voiced by Jonathan David Bullock/HeroicRoxas.
Check it all out in the video below.
