I can't wait for the film to come out either!
I think they ran a 'golden ticket' competition in Australia (or did I dream it?), but I think with the pending film it would be hugely successful and a great idea!
If Wonka chocolate had exclusive rights that would however be a great tragedy. Surely the marketing companies must realise that this chocolate is dire, and therefore pass the rights onto a decent choc company, like Mars (even more reason to buy Galaxy)!
