I absolutely LOVED this film.  It is movies like this that remind me of why I started this project in the first place.  It is so clever, so exciting, and so well executed that even today, it rivals all other action comedies.  Buster Keaton is a genius, and he plays the engineer on a Southern locomotive.  When the Union spies steal it, he chases after them to retireve it, only to wind up behind enemy lines and thrust into being a hero.  If you thought two trains chasing each other on one rail would get boring, think again.  The things this movie comes up with just leaves a perpetual smile on your face.  I enjoyed this movie so much in its whimsical simplicty, it is easily now one of my favorite films of all time!!!
