Dont you just love how they make the castle black and white, and smack him infront of it and pretend it's WDW's opening day?
Well, to be honest, I think the commercial was purposely done poorly (images roughly put together, I mean) so that people would KNOW it wasn't deceptive.
Very much not unlike using Bogart in that Coke commercial. It's like, "Yeah, everyone KNOWS what we're doing here with our new technology. If you drink Coke, you could be new technology, too!"
Trust me, it could be done a lot better. I've seen commercials that look extremely realistic only to be notified that that it's just computer generated.
My theory: every "mistake" in WDW/DL commercials are put there on purpose by WDI. They're like Hidden Mickeys. "Did you see the Matterhorn in that WDW commercial?" Well, that's just for you, the serious fan, to catch.
