Marvel Studios would be making a mistake not to sign this guy.
I know there's a lot of folks suggesting he play Dr. Strange, which I would be 110% behind, but none the less.. this actor seems like a perfect grab up for SOME MCU franchise:
* He's relatively unknown until now (like most of the headlining Marvel roles)
* He's clearly shown to be massively charismatic
* Really good at delivering the kind of banter MCU movies are known for
* Has the right look/age for several upcoming Marvel movie characters
* Can convincingly handle a weapon (not talking the stunt work, just the close ups) and would be a solid bet for action scenes
I'd honestly be more surprised if we don't see this happen, but it really should.
