However, Deadpool heading to the Disney/Marvel Studios umbrella was a cause for concern. After all, would Disney actually produce an R-rated film or would the House of Mouse tone down the ‘Merc with the Mouth’? According to the co-writer of Deadpool, it’s the latter. In an interview with EW, while out doing promotion for Zombieland: Double Tap, Deadpool co-writer Paul Wernick, had this to say:

This seems to align with what Marvel Studios chief Kevin Feige said back in April: “When we were purchased, Bob [Iger] said to us, ‘if it’s not broke, don’t fix it. There’s no question that Deadpool is working, so why would we change it?” But, it does slightly contradict what Deadpool 2 director David Leitch told Yahoo Movies in August: “It’s rated R so that’s not necessarily the [MCU] brand but he doesn’t necessarily need to be R and [Disney] don’t necessarily need to only make PG-13 movies. I think we’ll find a happy ground.” Another interesting thing to note about Paul Wernick’s comment is that he and his co-writer Rhett Reese are hopeful that Marvel Studios would allow Deadpool to veer into the Marvel Cinematic Universe sandbox. But if Deadpool remains R-rated, how would this work? I guess, considering the fourth-wall-breaking nature of the character, it’s always possible that in an MCU crossover, Deadpool looks into the camera and says something along the lines of, “I got invited to play with the big boys, but was told to behave myself.”
