Deadpool 3 will be the first R-rated movie ever in the Marvel Cinematic Universe.It comes after sources hinted that the Ryan Reynolds movie would carry the same certification as previous instalments, last November.Speaking to Collider during a WandaVision press event, the Marvel Studios president said: “It will be rated R and we are working on a script right now, and Ryan [Reynolds is] overseeing a script right now.“It will not be [filming] this year.

Ryan is a very busy, very successful actor. We’ve got a number of things we’ve already announced that we now have to make, but it’s exciting for it to have begun.

Again, a very different type of character in the MCU, and Ryan is a force of nature, which is just awesome to see him bring that.
