6. Kit Harrington
When Kit Harrington was cast as Dane Whitman in Eternals, fans were eager to see the groundwork laid for Harrington to become Black Knight. However, it's starting to look like we might never see that come to fruition, so if Marvel isn't going to put Kit Harrington's talents to use, then James Gunn most certainly should.
Harrington has all the qualities needed to bring Batman to life on the big screen. He has a commanding presence, incredible physique, and brooding intensity that are all signatures of the Dark Knight and a must when it comes time to cast the role.
As we saw in Game of Thrones, Harrington has the ability to craft complex, morally ambiguous characters which is crucial to convey Batman's internal struggles and the duality of Bruce Wayne. Bruce Wayne's internal conflicts require an actor who can convey both vulnerability and strength convincingly, a balance that Harington can strike effortlessly as he's proven time and time again.
In the DC universe, Batman is not just a superhero; he's a symbol of resilience, justice, and the indomitable human spirit. Harington's undeniable charisma coupled with his ability to convey the depth of character essential for Batman makes him the ideal candidate to suit up as the Dark Knight makes his debut in the new DCU.
