I vaugely remeber seeing a Majora's Mask commercial or preview that disturbed me a little, it was about two minutes long and it was as if the moon was going to fall in reality and its fate rested on one kid. It was done in a sort of documentary style with radio clips and people waiting outside waiting for the moon to fall, man it was really creepy, almost scary.
I found it on YouTube, and I think it's worth checking out.
