Wolverine?
I didn't know of him until I've watched The Legend of Hercules. Although Kellan is Hercules, Liam got my attention and I just thought he could be Wolverine (Kellan too).
I'm not in the badwagon of those who think actors can't be replaced. I LOVE Hugh Jackman as Wolverine (I would so love to see him crossover with the Avengers in Infinity Wars as his last part). Love, love, love! But I do not want to lose Wolverine. It is a matter of finding someone right for the part as they did for Batman with Keaton, Bale and it seems that Fleck too (did not see BvS).
