Chicago Reader review:
Buster Keaton's 1923 film, based on the Hatfield-McCoy feud. With this work, Keaton began to display a dramatic sense to complement his comic sensibility—like The General, it is built with the integrity of a high-adventure story. Of course, Keaton still finds room for his inimitable sight gags and beloved gadgets, here including an early steam locomotive that pulls its carriage train up and down the hills of Pennsylvania with a lovely reptilian grace.
Here (and above) is a trailer for the movie.
