I remember when the album first came out, everyone commented on the "catch a cannon ball" line, saying that it was a Kung Fu Panda reference. At first I thought, why? That's such a random reference. Now that I think about it though, it makes perfect sense since the director of Kung Fu Panda was collaborating with Coldplay the entire time! I wonder if there are are any other hidden references to his work in the album or comics.
