Like the notorious inflation adjustment that gives Gone With the Wind (1939) the unbreakable box-office high, a slight technological adjustment given the time (109 years ago!) gives Arrival of a Train at La Ciotat (1895) the best special effects ever (relatively speaking, of course). Forget King Kong (1933), throw out Star Wars (1977), Arrival of a Train' blew audiences away with a little thing called moving pictures. There's a classic rumor of audiences running away from the movie screen, expecting the train to crash right through! As scary as Kong was, nobody expected him to reach into the audience and pick out a few snacks!
Also, it may not have been all that intentional, but the composition of this static, one-minute shot is excellent, and still unrivaled. The perspective of the train zooming past the lens like a wild stampede, the quick stop, then, the explosion of activity: people coming, going, on the train, off the train. What crisp energy! What a film! Viva la Lumiere!
