If you were hoping for an R-rated Marvel Studios film, don't hold your breath. Marvel Studios president Kevin Feige told The Hollywood Reporter and other reporters that he doesn't have any plans for an R-rated Marvel Cinematic Universe film.

However, that doesn't mean he frowns on R-rated comic book adaptations. He praised Fox's R-rated "Logan" and "Deadpool" films, saying, “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. That should be the takeaway for everyone.”

According to Feige, both of these Fox movies are more than their R-rating; he cited the rating as a doorway to creative opportunities, which allowed the films to highlight "Deadpool's" humor as well as the brutal finality of "Logan." As such, both "Deadpool" and "Logan" have carved out unique spaces in Fox's "X-Men" universe, all while pulling off massive box office success. "Deadpool" has earned more than $783 million worldwide despite not opening in China, and "Logan" has climbed to $603 million and counting, which means their R-ratings were no barrier to their success.

Fox isn't the only studio testing the water with R-rated superhero flicks. Though Warner Bros. hasn't yet released an R-rated DC Film in theaters, an R-rated version of "Batman v Superman: Dawn of Justice" appeared on the "Ultimate Cut" edition of the Blu-ray. Last month, a report claimed that Warner Bros is open to the possibility of making a fully R-rated film set within the DC Extended Universe, though that has yet to be confirmed.

What's more, Warner Bros. Animation has turned its eye on R-rated films. Just last year, the studio released an animated adaptation of "Batman: The Killing Joke," which scored an R-rating. The film, which is based on Alan Moore and Brian Bolland's controversial comic of the same name, explored adult themes and used strong language. Likewise, the animated adaptation of "Justice League Dark" also received an R-rating, which shows that Warner Bros. is interested in expanding its R-rated repertoire.

However, it looks as though Marvel Studios won't follow in these dark and gritty footsteps.

Written and directed by James Gunn, “Guardians of the Galaxy Vol. 2" -- the next installment of the Marvel Cinematic Universe -- stars Chris Pratt, Zoe Saldana, Bradley Cooper, Dave Bautista, Vin Diesel, Karen Gillan, Pom Klementieff, and Kurt Russell. “Guardians of the Galaxy Vol. 2” arrives in theaters May 5.
