Keanu Reeves is looking to have a very exciting next couple of years as he has two big franchise movies on the way. Later this year we're going to get The Matrix 4 and in just under a year we'll have another big part four: the fourth chapter in the John Wick franchise. That movie has been putting together its cast in recent days, and has been adding some strong names including the likes of Donnie Yen and Scott Adkins. However, it wouldn't feel like John Wick if a few of the previous cast members didn't join Reeves back in the new film, and it's now confirmed that Lance Reddick's Charon will be back as well.
Deadline confirms the return of Lance Reddick to the franchise, which would seem to indicate that we'll see Ian McShane's Winston again as well. Although, as of now that has not been confirmed. It's possible contract negotiations are still being ironed out and that a deal has not been struck. While it's certainly possible we could see Charon return without Winston, the two have been largely joined at the hip throughout the John Wick franchise.
Lance Reddick has played the Concierge of the New York Continental hotel since the first movie, and he joined Keanu Reeves in the action-packed finale of John Wick: Chapter 3 - Parabellum, fighting off hoards of soldiers from the hotel. By the end, however, he stood by Ian McShane's Winston when he apparently turned on Wick and tried to kill him.
Lance Reddick joins Laurence Fishburne who is also confirmed to return to John Wick: Chapter 4 as the Bowery King. When last we saw Keanu Reeves' character in Chapter 3, his battered body was being dumped in front of the King, who also barely survived the events of the film. It seems likely that the two will be working together to get some measure of revenge.
Beyond that, we don't really know what John Wick: Chapter 4 will be bringing to the (high) table. Each movie has deepened the lore of John Wick's world of assassins that exists just under the surface of our own, in a way that normal people seemingly never notice what's happening around them. And the story will dive deeper still as we know that at least one more John Wick movie will follow this one.
Hopefully we'll see even more characters from earlier in the John Wick franchise return as well. While most people who go up against John Wick don't survive the movie, we could see Asia Kate Dillon's Adjudicator return, and there's even the characters played by Ruby Rose and Common from John Wick: Chapter 2 who never actually died on screen, and thus could technically return at some point. John Wick: Chapter 4 is currently set to open May 27, 2022.
