The Process of Faking It

After Joss Whedon announced that Avengers: Age of Ultron would not feature a post-credits scene, some filmmakers immediately set about creating a hoax. They constructed a fake post-credits scene that would have been the first introduction of Spider-Man into the Marvel Cinematic Universe. It was a very convincing scene that had me fooled for a little bit until it was, indeed, reveal to be all an elaborate prank. But the effort that went into it is fascinating and can be seen above if one would happen to be interested.
