Margo Martindale
A quick scan of her credit list shows that I have seen her only in this movie and in Dexter. Both times, she has played a mother/mother figure slowly dying in a hospital bed giving wise counsel to her stalker/serial killer son/son figure on her way "out". Weird
Build a man a fire, he's warm for a day. Light a man on fire & he's warm for the rest of his life!
