While speaking with Collider, Marvel’s Kevin Feige has reaffirmed previous details about Deadpool 3 that the film is rated R and will be indeed be set within the Marvel Cinematic Universe, the latter seemed to be slightly up-in-the-air given the maturity of the franchise.
FEIGE: “It will be rated R and we are working on a script right now, and Ryan’s 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 character to life.”
We officially know that The Molyneux Sisters from Bob’s Burgers are currently writing the film alongside Reynolds overseeing that work. Oddly enough, previous screenwriters and producers Paul Wernick and Rhett Reese were absent from trade articles concerning the new script suggesting they might not be involved creatively.
Deadpool 3 would likely mark the first mutant film for the studio and be released before the main X-Men reboot. What I think fans are still curious about is if the previous two films will be treated as canon moving forward and if they’ll bring back folks like Josh Brolin as Cable.
It’s still slightly unclear when they plan on shooting it, who will direct it, and what branch of Disney will ultimately end up distributing.
