After the train station clerk is assaulted and left bound and gagged, then the departing train and its passengers robbed, a posse goes in hot pursuit of the fleeing bandits.
Or maybe viewers have always relished the sight of the good guys blowing away bad guys, which existed in films since "The Great Train Robbery" in 1903.
This is why there are so many trains in movies, from 1903’s “The Great Train Robbery’’ on, and this is why “Unstoppable,’’ whose sole premise is right there in the title, works like a well-oiled charm.
Estos existen desde los comienzos del cine con relatos como «The Little Train Robbery» (1905) que se reía de «El gran asalto y robo al tren» (1903) mediante un cortometraje donde se recreaba la historia original con un cast de niños y un tren pequeño, ambas dirigidas por Edwin S. Porter.
