During the Credits
As Marvel Studios President Kevin Feige previously confirmed, there is in fact a brief extra scene during the credits of Avengers: Age of Ultron. It begins about two minutes after the credits begin. Check out full details hidden below.
After the Credits
Those who have attended early pre-screenings have confirmed that director Joss Whedon was not lying when he said that there is no stinger after the credits of Avengers: Age of Ultron.
The “leaked” extra scene with Spider-Man has also been confirmed by its creators as a prank.
Special thanks to reshef316, Mac, Rossatron, Cid, and Jack for the stinger submissions!
