This goes for both Ian and Kyle as they are brothers. I would think we are looking for someone tall, muscular, pale, black hair, and blue eyes. And don't forget acting abilites. I was thinking they could probably cast Ian and Kyle roughly the same time as the characters look so much alike. The only good Ian/Kyle I can think of is Daniel Cudmore. Duh! But I really have no idea. I'm gonna have to go study some of my movies!
Okay Henry Cavill in this picture
Henry could pull the Ian/Kyle if he were to seriously work out. Put on some muscle and he might be able to pull it off.
