You probably know that Fox has been distributing different copies of Wolverine to theaters: so if the main ending is the same for all, there are actually more than one after-credits scene.
Well, fellow fans are already sharing online clips of those Wolverine after credits scenes that they snatched with their phone cams:
1. Wolverine in a Japanese bar.
This scene is setting things for the Wolverine movie sequel: Wolverine 2 is indeed likely to explore the Japanese ark. More at: --> Wolverine 2
Deadpool will get his own spin-off movie: --> Deadpool Movie
--> Wolverine After Credits Scenes here!
I love the concept of different endings of Wolverine being shown in theaters: hope to see more companies doing it!
