I saw X-Men Origins: Wolverine (2009) which was in essence a revenge movie with lots of CGI effects.
Right at the end of the credits was an extra scene where Wolverine is drinking at a bar in Japan. When the bartender asks if he is drinking to forget, he replies that he is drinking to remember.
There is an alternative post credits scene where the final ultimate fighter Weapon XI having been decapitated is seen in the rubble stretching out his hand to retrieve his head.
Both post credits scenes are supposed to herald 2 separate future films.
