You could take all the cool people you know, tie them together and melt them down into one pile of fleshy coolness...and it still wouldn't be as cool as Kate Beckinsale. She could wear a Wal-Mart vest and still look better than most people.
I'm not sure who that guy is with her, but I assume it's her husband or bodyguard. And since bodyguards are usually 6'8" and black, it must be her husband. I hate him, but there's always the chance he'll get in a boating accident.
