(Mods, I've cross-posted this in the UK forum - if it's a problem, please delete.)
Check
this out. It's a live-action Simpsons promotional ad made by SKY TV in the UK - not on TV yet, so I'm wondering when they'll introduce it. My only quibbles are that it's obviously not the USA, plus Marge's hair isn't blue. Also (and I say this as a sax player), the little girl playing Lisa doesn't do a very good job of faking it; she looks like she's about to swallow the entire mouthpiece of her saxophone. Other than that, it's very cleverly done and must have cost an absolute fortune to film.
