Deadpool 2 is still early in its production process, but fortunately its raunchy predecessor is a gift that keeps on giving. Deadpool took the world by storm last year, becoming one of the most successful rated R films ever, but some moments on set reached a level of vulgarity that not even the Merc with a Mouth could land in the movie's final cut.

The actors and crew appeared to be having just as much fun making the movie as the viewers later would watching it, and the behind-the-scenes peek also gives a glimpse at the level of improvisation the actors were allowed when filming. In particular, Ryan Reynolds and T.J. Miller appeared to be given almost free reign during some of their scenes to spout whatever obscenities came to mind, many of which presumably did end up making it into the movie.

At one point, Ryan Reynolds even makes a pretty keen observation on how Charles Xavier's naming conventions leave much to be desired. "Seriously? It's called the X-Men? I mean, there are women here, right? It's very sexist," Deadpool remarks to an agreeing Negasonic Teenage Warhead.
