The time has come for Ben Affleck to officially retire his Batman, ing the baton to a new actor. The new version of Bruce Wayne will make his debut in Matt Reeves' movie, set years earlier in the Dark Knight's career. And with the casting now underway, we have a few actors in mind that we're certain who could play a younger Batman.

We won't be alone, as rumors of Ben Affleck's departure have circled since before Keanu Reeves would rather play Wolverine, we've assembled our list of other actors who could be relied upon to fill Ben Affleck's empty, and slightly younger shoes.

A quick note on our selections: since director Matt Reeves has said his sorry, Jon Hamm fans).

6. Ben Barnes

Ben Barnes Son of Liberty

Even though his star was rising since before he played a villainous black-hat on HBO's The Punisher's Billy Russo, opposite star Jon Bernthal. And if a superhero is only as good as as his villain, then Barnes is due as much credit for the Netflix show's reception as its hero. Frankly, we're still not sure how the Narnia series' Prince Caspian played a smooth-talking New Yorker so seamlessly.

Those unconvinced or simply unfamiliar will want to make time for Barnes' recent filmography (on either side of the Atlantic). But in a nutshell, both seasons of The Punisher have demanded Barnes be as convincing as a top-tier Marine, a slick executive, and a deeply broken, darkly vulnerable and traumatized survivor. Basically everything that any director could ever need from a movie version of Bruce Wayne.

5. Nicholas Hoult

Nicholas Hoult Rebel in the Rye

By this point its safe to say Nicholas Hoult has proven himself one of the most versatile, if not one of the very best actors of his generation. Whether blockbuster fans know him best as one of the playing Hank "Beast" McCoy of the movie X-Men, but that is going to be less of a problem in the near future (fora number of reasons).

Even giving once Disney attains the rights to the X-Men universe, it's probably best that Hoult weigh his options now. Especially if a pair of lenses is all it takes to have fans saying "Beast who?" (see above).

4. Jake Gyllenhaal

It's time to begin weighing the actors who have already been rumored in the conversation of a potential replacement for Ben Affleck, back when his departure was murky, at best. In fact, reports singled out Gyllenhaal didn't explicitly deny Batman talks when asked about the rumors in an interview. Even if other names have been mentioned since, the first word may remain Plan 'A'--and with good reason.

In a sense, both Gyllenhaal and Affleck dealt with the challenge of being typecast in their younger days for their leading man looks and charms. And both eventually changed that reputation, elevating their names to the realm of Oscar-caliber talent. Now, the only real question mark attached to Jake Gyllenhaal's 'ability' to play Batman is where his role as Mysterio in Spider-Man: Far From Home leaves him.

Jamie Dornan Death and Nightingales

3. Jamie Dornan

This choice may be too easy, since few actors have proven to be as skilled as the modern Ben Affleck at portraying quiet, intense, dangerous, handsomely brooding protagonists as Jamie Dornan. The Irish actor may be most widely known to American audiences as the infamous 'Christian Grey' of The Fall (a role and series that has earned critical acclaim).

It's impossible to tell which path Warner Bros. and director Matt Reeves will want to take with their next Batman: choose an actor of comparable star power to Affleck to build excitement, or one lesser-known to American fans (or to blockbuster movie audiences) to drive home The Batman as its own version of the character. Dornan has the smarts, the physique, and the darkness needed to deliver a serious Batman drama, so the only question is whether or not that's what the movie will be aiming for.

2. Finn Wittrock

Finn Witrock Unbroken

Finn Witrock's name is likely to be familiar to fans of the DCEU's Batman Family, since his name emerged as a rumored contender for the star of DC's mysterious Nightwing movie. That film may have been one of the first officially greenlit entries in DC's growing movie universe, but momentum has stalled following Justice League and DC Films' restructuring. However, Witrock was embraced by many fans as a suitable actor for Dick Grayson, and made it clear he would love to be considered. So if he was good enough to play an older Robin, would a younger Batman fit just as well?

Witrock is guaranteed to be up to the physical challenges of the role, since he has spoken openly about his rigorous training regimen required for his role in Semper Fi, currently in production (alongside the DCEU's Captain Boomerang, actor Jai Courtney). And let's be honest: the fact that he looks like a Mikel Janin drawing of Batman come to life can't hurt his chances.

1. Jack O'Connell

Finally we arrive at the other actor rumored to have been on Matt Reeves' radar, and certainly the more intriguing contender. When the first reports suggested that the existing DCEU Zack Snyder created.)

If Matt Reeves is looking to tell a dramatic, intelligent, pull-no-punches detective story, then his interest in O'Connell is easy to understand. In all honesty, his casting may depend on whether Batman is a role O'Connell wants to pursue. But where there's smoke of a potential casting there is often fire. And something tells us he could be talked into it.
