This is amazing! One of the cooler vids I've seen in a while. Prepare to have your jaw drop when you check out the behind-the-scenes video. I would have probably gone mental assembling the 280,000 jelly-beanies in the billions of scenes. Which makes it all the more commendable for the team at work.
The amount of talent on Youtube - be it singing, dancing, directing etc - is immense.
