With Avengers: Endgame, directors Anthony and Joe Russo wrapped up their four-movie stint with the Marvel Cinematic Universe. Although the two are done with Marvel movies for the time being, the duo admitted that if the right opportunity arose, they'd love to come back -- specifically if given the chance to work on a film about Doctor Doom and the Fantastic Four.

"I love Ben Grimm from the Fantastic Four," Joe Russo told Business Insider. "Doctor Doom was always one of my favorite villains." He added that he loves Wolverine and other X-Men-adjacent characters. However, he admitted that the Clawed Canuck would have to be "set aside for a little while." After all, the character -- as played by Hugh Jackman -- was the primary focus of Fox's X-Men movie franchise for 17 years.

With Disney recently acquiring Fox, Marvel Studios now has access to the X-Men and Fantastic Four characters. Nevertheless, Marvel Studios President Kevin Feige has stated that they won't use those characters just yet.

Directed by Joe and Anthony Russo, Avengers: Endgame stars Robert Downey Jr. as Iron Man, Chris Evans as Captain America, Mark Ruffalo as Bruce Banner, Chris Hemsworth as Thor, Scarlett Johansson as Black Widow, Jeremy Renner as Hawkeye, Brie Larson as Captain Marvel, Paul Rudd as Ant-Man, Don Cheadle as War Machine, Karen Gillan as Nebula, Danai Gurira as Okoye and Bradley Cooper as Rocket, with Gwyneth Paltrow Pepper Potts, Jon Favreau as Happy Hogan, Benedict Wong as Wong, Tessa Thompson as Valkyrie and Josh Brolin as Thanos.
