Keanu Reeves is back for John Wick: Chapter 3, which has just hit theaters. That’s right: John Wick is back for a third go-round. But after battling badass assassins and countless unnamed bad guys in the first three films, Reeves needs some new blood (literally) for the cast of the potential fourth film. It’s potential no more: Lionsgate announced in a message to fans that John Wick: Chapter 4 is coming on May 21, 2021.

So: Who will he fight next? Reeves does most of his own stunts, dating back to his days on The Matrix, and the John Wick series is no different.

“There’s an incredible stuntman who doubles John Wick,” Reeves told Men’s Fitness in 2017. “They hit him with a car. He’s standing there, and they hit him—that’s a stunt. Me? I’ll shoot some guns, flip some people—and that’s action. So, yeah, I do as much action as I possibly can, because I love it—and I love the opportunity to bring the audience along. I want to be able to do everything. Since The Matrix, I’ve used this term, ‘super-perfect’. As in, ‘Can we get it super-perfect?’ That’s part of what makes [a great action film] a pressure cooker. It’s the intensity of just trying to do the best you can in the circumstances that you have.”

We asked Men’s Journal readers their best suggestions originally for the third film, but now that the movie is coming out, what about a fourth movie? If any of these dream cast options end up in the potential film, expect one of the biggest, most badass action movies ever.

Here’s a look at who you think John Wick should battle in Chapter 4, ranked according to their action-movie experience, skill at portraying villains, and cinematic track record.
