British horror films in which the Americans are the coolest characters

Severence. The character of the American heroine is cute and plucky and all the guys are in love with her. It's really a good movie, as far as horror movies go.

Outpost. The redneck, mercenary character is very cool indeed. He's played by Richard Brake, who's from Wales, but does a bang up job acting as an American. His bio says he lived in the American south, which would explain his excellent imitation of a southern American. He reminds me of Chuck Norris, well, if Chuck were a much better actor. The movie also stars the big and handsome Ray Stevenson, from HBO's, series Rome.
