So this isn't at an AMC, it's at SIFF cinema, but it's a documentary that's supposed to be really good. With Teen Tix you can get in for $5, for adults its more. http://www.seattlefilm.org/events/detail.aspx?FID=76
It's a 7:30 show, and even if it's not the Monday movie, let me know if you're interested in seeing it with me sometime this week (it's playing until Thursday.)
Except not Wednesday, because I work.
