The General/Awesome

The Buster Keaton film

 * Johnnie Gray deciding to get back his girl and his engine.
 * Johnnie Gray beating every trap the Union lays for him.
 * Johnnie Gray finding the General at the Union yard and storming into the cab, retaking his engine at last.
 * The shot of a locomotive falling through a bridge into a river, the single most expensive shot of the entire silent era.
 * The cannon sequence, keeping in mind all that was done when computers, let alone CGI, were decades away so everything that's happening is 100% real and had to be timed accordingly. To get one shot, Keaton had to measure out the cannon's powder charge with tweezers.
