In X-Men 2, when the SWAT team invades the mansion, there is a guy with face paint, I think he's the head SWAT dude, he is standing alone in a hallway while the team silently takes position behind him. Then(I think) he sees the "electroboy" and shoots him in the neck. He's done other movies but I don't know his name.
Everytime I see that guy in that scene, in my head I go SNAAAAAAAAAAAAAKE!
