I really enjoyed this film too. Greed is a monster of it's own from what I remembered in this beauty. Billy Bob seemed to play simple minded people in the 90's for some reason or maybe I'll always remember him from Sling Blade?
Bill Paxton always stuck out as an interesting casting choice. Not sure if you've seen it but he directed a film called Frailty (2001). I need to watch this again but it did stick with me for one reason or another.
I haven't seen Frailty, but it looks like an interesting recommendation. I'm going to add it to my list.
