Regardless, the fact that they're even considering that Jesse McCartney for Zuko tells me they're not going to even try to match the characters -- major ones or minor ones -- up with actors/actresses that resemble them. They need at least a year for shooting, I imagine, so I'd say they're going to finish up the casting pretty quick.

I don't have a problem with over 18 actors -- lots of people in their 20s, dressed appropriately, could pass for teenagers. But there are TONS of 20-something ethnic actors too, and IMO they really should have kept to the style of the show (and its thematic origins, which are definitely not American/European). -___-
