Deadpool 3 is going to be a first for the Marvel Cinematic Universe in more ways than one. Not only will the threequel be the first ever Marvel Studios R-rated release, but it will also incorporate several characters from the now defunct 20th Century Fox era of Marvel-based movies into the MCU (though it's worth mentioning that Doctor Strange in the Multiverse of Madness did feature Patrick Stewart's Charles Xavier in an alternate universe-set sequence).
The movie's main duo, Wade Wilson (Ryan Reynolds) and Logan (Hugh Jackman), obviously started out under the Fox-Marvel banner, and even though they will officially become part of the MCU in Deadpool's latest adventure, director Shawn Levy has confirmed that the "Fox legacy" will be "part of our storytelling."
"Deadpool and Wolverine are iconic Marvel characters; more specifically, iconic Marvel-of-the-Fox-era characters," said the filmmaker during an interview with Total Film. "We’re not going to pretend: 'Oh, we snap our fingers, and suddenly that Fox legacy doesn’t exist, and it shaped a lot of what we now know as the MCU.' Fox also shaped Ryan’s career, Hugh’s career and my career. So there’s a lot of history there, and there’s a lot of Marvel history at Fox. And certainly that’s a part of our storytelling."
There have been numerous rumors relating to certain characters making cameo appearances, not only from the X-Men and Fantastic Four movies, but even the likes of Channing Tatum as Gambit - who never actually got to make his debut before the plug was pulled on his solo movie.
So far, the only confirmed appearance outside of Reynolds and Jackman is Jennifer Garner's Elektra, but if she's involved, you can bet that at least some of the other names we heard will also be showing up.
Morena Baccarin (Vanessa), Karan Soni (Dopinder), Leslie Uggams (Blind Al), Rob Delaney (Peter), Brianna Hildebrand (Negasonic Teenage Warhead) And Shioli Kutsuna (Yukio) will all return as their respective characters, and they'll be joined by franchise newcomers Emma Corrin (The Crown), who is believed to be playing Cassandra Nova, and Matthew Macfadyen (Succession).
Specific lot details remain a mystery for now, but Wade and Wolvie are expected to find themselves (trapped?) in the Marvel Cinematic Universe. A recent report claimed that Loki's TVA, including Agent Mobius (Owen Wilson) and Miss Minutes, will be involved. We have also been led to believe that Wade's MCU debut will be far more integral to Phase 5 and beyond than we first realized.
Deadpool 3 is set to hit theaters on September 6, 2024.
