The theater I purchased tickets at a while back originally only had it showing in one theater for a midnight show, but when I checked their website earlier today, they had added a 12:10 showing and a 12:20 showing. I suppose that there must have been a demand for it, so I'm hoping they make three separate lines so nobody gets mixed in with other showings by accident.
I am actually more worried about my staying awake than I am standing in line right now. I don't doubt that I'll be able to keep my eyes open during the film itself, but I probably won't get to bed until 3 AM, and that's later than I've been awake in three years (since AOTC). I had the same worries when I saw AOTC, but after seeing it, I was actually all hyperactive, so I'm hoping I'll have the same effect this time.
