"There's no such thing as adventure. There's no such thing as romance. There's only trouble and desire." It's probably the best-known phrase of this movie, but actually it's a quote from Fritz Lang's movie Dr. Mabuse the Gambler (1922).
Kate, this man we're dealing with is quite possibly a dangerous criminal.
Kate: How do you know?
Sheriff: What do you mean how do I know?
Kate: What is it that makes a man dangerous anyway?
Sheriff: Look, I'm asking the questions here, okay.
