During the second trailer, when Pitch says, “What an adorable dream?” we see that the girl is dreaming of someone riding a unicorn. (It’s the best picture I could get, but I assure you it’s the girl dreaming of someone riding a unicorn.) Then, in the “Making Dreamsand” Featurette, I noticed that the girl is then standing next to a life sized unicorn made of dreamsand.
Gosh darn it Dreamworks! I really didn’t think your attention to detail could get any better, yet it did.
