He looks like

When he is clean shaven I think he looks like Simon Tam from Firefly.

A cross between David Giuntoli and Liam Hemsworth. Also, he kinda resembles Justin Bartha, IMO.

I don't know why, but he reminds of Adam Levine.

I think my mask of sanity is about to slip.

Eddie Cahill

Who wants to live forever?

Liam Hemsworth/ Armie Hammer

Oh my gosh, yes!

I don't see those two but I do see him looking like Joseph Fiennes, Michael Fassbender, Eddie Cahill, Rob James Collier, and Glenn Frey. I also say Glenn because if a movie, miniseries, or musical ever gets made soon about The Eagles Colin is my pick for Glenn.

Yes!!!! Eddie Cahill and Joseph Fiennes, the best bits of each!
