Actor doppelgangers from the new Netflix show Fool Me Once

The actor who played Shane and the actor who played Marty both reminded me of some American actors who I can't place.

If I look at a still photo (like his IMDb photo) the one who played Marty kind of looks like Scott Adkins, but that is not who he made me think of while I was watching the show. I can picture the actor, he's young - probably late 20s or very early 30s.

The one who played Shane, looks so much like someone and I can't shake my brain to remember who it is he made me think of.
