First, Ryan Reynolds showed off his Deadpool costume for the upcoming movie, now he's showing off his Mario Lopez killing skills as Deadpool.
The whole video is wrapped around a discussion of the 2016 movie's rating. But given that it seems to be a joke and that it falls on April Fool's Day, I'm not sure that you should put much weight on the conclusion here that the movie will be R-Rated.
Update: Fox has confirmed to CBR that the movie will indeed be rated R and that the April Fool's joke was that it was going to be rated PG-13. The headline has been updated to reflect the confirmation.
