Jason Dottley (33 today) is one of those guys I came across in one of my birthday searches. I'm not strongly motivated either way about him, but he's nice enough looking, which fullfills my minimum wallpaper making requirement.
Xavier Samuel turns 30 this week. He got his first wide exposure in one of those movies. I think he'll be getting more work after that. Especially since he looks that good in board shorts. See more of him on Tumblr.
Nicholas Hoult is 24 this week, but looks like he's 16. That could be useful in having a long career. He's a Brit who started in TV, but now is appearing in all sorts of movies. See more of him on Tumblr.
DeCoteau Dude this time around is Connor Weil. He's a pretty one, ain't he? Connor seems to be more of an actor, doing the modelling to pay the bills. He's been in one of David's 1313 series movies, 1313: Frankenqueen. Frankenqueen, really? Ooooo-kay. He's on Twitter, if you're interested. He can also sing, as this indicates. It doesn't sound too AutoTuned, so maybe it really is him.
