Over here in the UK, there is currently an advert on ITV with Chewie in it. It could be a breakfast cereal.
I have also just been to see the preview showing of Hitchhikers Guide to the Galaxy and there is a FANTASTIC Orange (UK mobile phone company) ad starring Darth Vader with a couple of Stormtroopers. These ads usually make it onto TV.
As I said, only partially relevent to this thread...............
