"My, my, my, my, my, what a mess." -- Deputy Marshal Sammy Gerard (Tommy Lee Jones) eyeing a train wreck.
I've actually been to the place where they filmed the big train-and-bus wreck! They used a real train and a real bus, not models, and it was the biggest wreck ever filmed to that date, IIRC. They filmed it up on the Great Smoky Mountain Railway in North Carolina, and they filmed some of the chase stuff in that area too, like the river that Dr. Kimble swims in after he does a Peter Pan right offa that dam.
Man, I love this movie.
