Fake or Real Avengers: Age of Ultron: 'After credits' scene leaked

Hail Hydra, it looks like the after after credits scene for Avengers: Age of Ultron may have just leaked online, days before being released to the public.

Be warned, possible spoilers for Age of Ultron ahead.

While currently unknown whether the trailer is fake or not, if real we could be seeing the introduction of Spider-man into the Marvel Cinematic Universes much sooner than expected.

The apparent after after credits scene sees the web slinger telling a window cleaner he "missed a spot", with the Avengers tower sitting in the background.

Spider-man has yet to be officially cast, raising serious doubts over the clip's authenticity.

However, Marvel films are known to introduce key characters in their post credits scenes, such as Thanos after the first Avengers and Scarlet Witch and Quicksilver after Captain America: The Winter Soldier.

Facts about Spider-man in the Marvel universe are sparse but we definitely know Andrew Garfield will not be reprising his role from The Amazing Spider-man and that the studio is looking for someone in their teens to play the role of Peter Parker.

Avengers: Age of Ultron is set to hit UK cinemas on 23 April, while a Spider-man film is set for release on 28 July, 2017
