Hey, LMouse. You said you hadn't seen many Smallville episodes. You might be interested to know that James Marsters (Spike) sans British accent was in some of the episodes during the last season of Smallville. He was a.. uh.. bad Kryptonian thing. Heck if I know what he was supposed to be. He was a follower or thing of Zod's.
Sorry if I've already mentioned that. Before I saw him on Smallville, I'd of sworn he was really British, but I read a couple of articles about his appearances on Smallville and he isn't British.
