Reminds me of the Amazing Honda Accord commercial - the Cog... Rube Goldberg machine all done without CGI (5 months of pre-work, then 605 takes until they got to one that didn't screw up somewhere) http://www.youtube.com/watch?v=_ve4M4UsJQo They did a lot of work that they could've avoided with CGI, but where would the fun be? Making of video: http://www.youtube.com/watch?v=Kh4zWeUDW-E
Another good one that is similar in the sense that they went through a whole lot of trouble is the Sony Bravia commercial http://www.youtube.com/watch?v=9NymcQJjPCs They did a lot of work that they could've avoided with CGI, but where would the fun be?
BTW, it seems Jelly Belly was in on the fun a little bit... http://www.jellybelly-uk.com/bean-world/page/?id=47 At the very least, I'd imagine that she didn't pay for the jelly beans
