Since Wolverine and Deadpool are unquestionably the two most prominent characters in the X-Men movie franchise, having them appear in the same movie is a no-brainer.
That said, let’s hope that this supposed Deadpool scene does take place after the credits have rolled, as Wade Wilson’s shenanigans would be a poor fit for Logan’s gloomy feel.
It would be even if greater if the two of them actually met face to face, as Wolverine’s gruff demeanor wonderfully contrasts with Deadpool’s smart-ass personality.
Their brief interaction in X-Men Origins: Wolverine was slightly amusing, but now that Wade is wearing the red costume and breaking the fourth wall, we could get something more in line with their interactions in the Marvel comics universe.
