As I've watched Lost for the last six years, I've always been struck by how many flippin' characters they have on the show. I don't mean just the cast of regulars, which I think numbered close to 20 at one time, but the one- (or two-) episode wonders who popped in for a quick guest bit in a back-story and were never seen again, usually because their characters died, as people tend to do on Lost.
So I watch all these shows, see all these guest stars, and know that I've seen them somewhere before, but just can't place where. I hate that, don't you? I bet you do, which is why I'm making this list. Yes, a little late, but life's a bitch sometimes.
