There's Another Audience Watching ME?!!
It took me more than a few watches to finally notice this one, but ICYMI, there's an undead audience of skeletons and people seemingly dressed in costumes watching the same movie scenes that we are — but from the other side. I'm still a little confused about whether this movie theater full of people implies that we, the audience, are dead, too. Either way, this creepy detail still gets me every time.
