An "Avengers: Age of Ultron" after credits scene has recently appeared in YouTube, introducing another superhero into the Marvel Cinematic Universe.

The video clip is forty-three seconds long and initially shows a window cleaner, wiping the building glass. As the man wipes the window, he reveals Spider-Man along the background. The web-slinger is talking to the man, but seems to be ignored.

Although the clip showed a bright way of introducing Spider-Man into the Marvel Cinematic Universe, the legitimacy of the clip is still questionable for few reasons, as per Comic Book Movie.

First, Spider-Man has not yet been cast in the role at this point. Another reason is Spider-Man's voice, which is unclear, preventing fans to distinguish the man inside the suit. Third, the video is not of a high resolution. And last, Marvel head Kevin Feige and film director Joss When previously mentioned that "Avengers: Age of Ultron" will not be having a post-credit scene.

The said scene must have undergone a lot of effort just for a trick, according to Inquisitr. While film helmer Whedon previously denied a post-credit clip for the film, it can still be possible for "Avengers: Age of Ultron" to continue Marvel's tradition of connecting its films with each other.

The "Shawarma" scene featuring the Avengers was not produced, but the production filmed it a couple of days following the premiere of the original "Avengers" film. To top that, everyone remained tight-lipped about the scene until the film's wide release.

Based on the earlier set-up made by Marvel, it is also probable that "Avengers: Age of Ultron" will surprise its fans at the end of the credits. But whether there is a post-credit scene or not, Ultron will push his plans to wreak havoc the Avengers and terminate mankind.

Helmed by Whedon, the film stars Chris Evans, Robert Downey Jr., Chris Hemsworth, Scarlet Johansson, Mark Ruffalo, Jeremy Renner, Aaron Taylor-Johnson, Elizabeth Olsen, and James Spader.

"Avengers: Age of Ultron" is set to hit theaters on May 1.
