People are starting to wise up and not leaving the movie theater soon after a comic book movie ends! X-Men: Days of Future Past is another movie that insists of having an after credits scene so it’s a good idea to sit down and wait for all of the names to roll off the screen before you stand up.

Also, if you’re a Marvel fan, please be prepared to brush up on your X-Men history as well since a majority of non-comic book readers are going to ask you what the after credits scene is all about.

You have been warned!
