As it is a Marvel movie, expect a post-credit scene or two for Thor: Ragnarok!
A film critic for Forbes posted that when he saw an advanced screening for Thor: Ragnarok that there were at least two post-credit scenes. It's possible there may have been more, but a bathroom break happened to get in the way.
It's further said the first Thor: Ragnarok post-credit scene was plot-related, with the second being some sort of joke.
There were two that I saw, but my son had to use the bathroom during the credits so it's possible I missed one.— Scott Mendelson (@ScottMendelson) October 9, 2017
The first is slightly plot-related but the second is a straight joke.— Scott Mendelson (@ScottMendelson) October 10, 2017
