Super Bowl ads

On the topic of super bowl ads, I really enjoyed the coke ad which had the parade with the monstrous balloons chasing after the coke balloon. It ended up with the Charlie Brown balloon winning the race to the coke bottle. Quite hilarious. The interesting thing that I found in regards to acting, is that in order for myself or anyone else to understand what in the world was going on, the balloons had to have some movements that would be typical to that of a human being's while still remaining a balloon. It would be some sort of combination between a balloon and a human. I would imagine that would be even harder than for a human being trying to act like another human being. Now you have a balloon trying to remain a balloon, but have some sort of action that would look similar to that of a human.
