Because he looks like he could be straight out of a Bond movie.
Seriously, if you have the chance and time to watch Move on, do it! It’s a German production (and they usually suck) and it’s not the best movie you’ll ever see (and the ending is quite strange), but it’s pretty good. And Mads is fucking gorgeous in that film.
EDIT: Goddamnit guys - I know he played Le Chiffre in Casino Royale. I meant he could be Bond in that scene.
