5. Karl Urban
This might be my personal pick! Geeks like us seem to love him so. He's the best piece of casting in the Abrams Star Trek as Bones McCoy, and he was wonderfully hardcore as Eomer of Rohan in The Lord of the Rings. And it is just plain unfair that his perfect portrayal of Judge Dredd in 2012's Dredd went without a sequel. This guy would be fantastic as the stern and often merciless Jones that we saw more of in Raiders of the Lost Ark. Though, having said that, he's actually pretty funny as Bones in those Trek movies. He could quip it while he whipped it.
What sets Urban apart from other candidates is his bonafides of playing a role very seriously in the middle of an inherently bonkers premise. Indiana Jones is a college professor who is thrust into his life-or-death adventures to secure mythical objects whose very existence can change human history. Urban played a space marine fighting demons on Mars in Doom, as well as an average joe detective teamed up with an android to solve crimes in Almost Human. If there's a guy who can be believable in the most unbelievable, it's him.
