Marvel Head Says Marvel Will Not Be Making R-Rated Movies, Spidey Will Be in Avengers 4, and Joss Whedon Made The Call for "Batgirl"

THR has the follwing courtesy of Marvel head honcho Kevin Feige:
Feige has no plans for an R-rated movie.
Don’t look for an R rated Marvel movie in wake of success of such bloody and potty-mouthed movies such as Logan and Deadpool any time soon.
“My takeaway from both of those films is not the R rating, it’s the risk they took, the chances they took, the creative boundaries that they pushed,” Feige explained. “That should be the takeaway for everyone.”
While the R-rating is an easy-identifiable trait of those movies, Feige cited the breaking of the fourth wall in Deadpool and the finality of the Wolverine story as examples of what made those movies stand out.
Joss Whedon called Feige about Batgirl.
Whedon spent years at Marvel not just as the writer and director of the two Avengers movies but also as a consultant, giving input on other projects. And thus when it was revealed he was taking on Batgirl for DC, fans were shocked at the news. It turns out Feige had known about it for a while. And was cool about it.
"He called. A couple months ago, which he didn't have to do and was super cool of him and super nice of him," Feige said. "And we couldn't be more supportive. We want to see a Joss Whedon Batgirl film be awesome."
Spider-Man is in Avengers 4 … and Marvel has no involvement in the Spidey spinoffs.
Marvel's landmark deal with Sony has allowed the wall-crawler to enter the MCU, and Feige confirmed Spider-Man will appear in 2019's untitled Avengers 4. That’s after his starring turn in Spider-Man: Homecoming and 2018’s Avengers: Infinity War.  After the second Avengers appearance, it will be back for a Homecoming sequel, set for 2019. 
“That’s as far as it goes for now,” Feige said. (For now? Hmm.) 
Sony is moving ahead with Spidey spin-offs for Venom and a Silver Sable, Black Cat teamup movie, but Marvel isn't involved.
"We had a very particular plan about Spidey himself," Feige explained when asked why Marvel wasn't involved in Sony's projects with those characters, although he kept those plans to himself.
James Gunn's role could extend past Guardians 3.
Gunn revealed Monday that he will return to write and direct Guardians of the Galaxy Vol. 3, and he teased that just as the first ten years of Marvel's movies built to 2018's Avengers: Infinity War, the third Guardians film would help set up the next ten years of movies. Feige suggested Gunn's relationship with Marvel could extend past that film, which does not yet have a release date.
"I think James in particular has an amazing connection with these characters and with this cosmic world. So he, I think, could easily oversee additional stories beyond Vol. 3," said Feige. "And I think has them and just continues to come up with them, which is cool. All of our core writers and filmmakers know what we are doing in other places and help give input on the various projects."
