Given the significance of the post-credit scene for superhero movies, it should come as no surprise to learn that Deadpool had not one but two. Moreover, while the two post-credit scenes were rather amusing, it should be mentioned that they provided interested individuals with a fair amount of information as well.
The first post-credit scene referred a couple of movies. One was Ferris Bueller’s Day Off, as shown by the bathrobe as well as the casual breaking of the fourth wall. Meanwhile, the other was a joke about the Deadpool movie not being Iron Man, which kicked off the Marvel Cinematic Universe by featuring Samuel L. Jackson in the role of Nick Fury in its post-credit scene. Some people have interpreted the scene to mean that Fox wasn’t interested in working with Marvel to make Deadpool as well as the X-Men movies part of the Marvel Cinematic Universe, which was what had happened to Spider-Man. However, it is important to remember that a lot has happened since that time, meaning that if Disney manages to buy out Fox as planned, that could well change. With that said, there has been no announcements of either said franchises being folded into the Marvel Cinematic Universe or even something that could be interpreted as a hint, meaning that it is still much too premature to speculate about the ultimate outcome of that one way or the other.
In contrast, the second post-credit scene was focused on the plan of the people behind Deadpool to introduce Cable in the second movie. Granted, this might have been a bit presumptuous on their part considering that they couldn’t have predicted the outcome of their moves with perfect accuracy at the time it was made, but considering that there is indeed a second Deadpool movie coming out very soon, it seems safe to say that their confidence in their product more than paid off. As for the inclusion of Cable in the second Deadpool movie, well, it could very well pay off, particularly since it has happened before in the comic books.
For those who are curious about the character, Cable is that peculiar blend of very serious and very silly that sometimes pops up in comic book, which is something that could work well with Deadpool. In short, Cable is the son of Scott Summers and Jean Grey from the X-Men franchise. However, Cable is actually older than either one of those two characters because he is a time traveler from a horrible future that he seeks to prevent. Moreover, while Cable possesses immense telekinetic powers because of his mother, he has to use his powers to keep a techno-organic virus in check, meaning that he actually uses guns when fighting even though he is supposed to be a ridiculously powerful mutant even by the standards of those who are featured front and center on Marvel comic books. Summed up, Cable is very blatantly the product of a very weird but very entertaining time in the comic book industry, meaning that he might just turn out well when brought to the movie screen via a Deadpool movie, which can balance out his very serious character background with its usual very unserious treatment of things.
