Barn is currently #2 after True Blood's Eric. That's not too bad - especially considering that Eric is current and extremely popular. (Though Barn does have Buffy's Spike (not surprising) and The Gates' Claire (very surprising, but certainly deserved) chomping at his heels and tied for #3.)
Well, that's often the case when someone does a bit part. In fact, it's quite often the case that they get cut entirely. I suppose we have the film's PTB's devotion to KLS to thank for the fact that any of her part survives in the film.
