Post-Credits Scenes

[Oateyboat]

Thought it would be handy to open up a thread, listing post-credits scenes that people may have noticed, in case any of us have missed parts of our favorite films out.
To all posting a scene, would it be possible to make it clear, as I have no doubt there may be posts without scenes in, by putting the films title in bold. Also, could you include a small description of the scene, and how far in it is.
Spoiler tags appreciated if needed. (To make a spoiler tag, simply type spoiler inside of these brackets [], and then /spoiler, inside the same [] brackets)
