With Revenge of the Sith around the corner I have a feeling that links like these will proliferate - if they're as good as these ones then the more the merrier!
Firstly, "Revenge of the Brick" - a really cleverly thought out merchandising promotion for Lego - tongue in cheek, lots of good gags and you have to watch until the end!
Secondly, Yoda Diet Pepsi commercial. Starring Yoda and Chewy - cute.
And lastly the Darth Vader / Orange tie up. Not as good as the others but worth a look!
