Just watched Carrie, and it's one of the best movies I've seen in a while. That's impressive, considering it was made in 1976. Looks like there will be a new one this year too. Dune also comes to mind (1984) as a fantastic old movie.
I just jumped to the center of the movie (Amazon Prime members can stream it for free) and watched the poisonous deadly snake scene. Went a bit like this:
Guy: What's that?
Trio: A box with a deadly snake.
Guy: Lies! I'm going to figure out how to open it.
Trio: *Spends a couple minutes debating slowly how to convince the guy.*
Humphrey: "He already knows."
