For a recent episode of Nerdwriter, Evan Puschak takes a look at how Steven Spielberg constructed the intense opening scene of Saving Private Ryan. His decision to film the Omaha Beach landing from the perspective of a battlefield cameraman — something he cribbed from actual WWII battle footage and John Ford's The Battle of Midway, where scenes in which on-set explosions made the film skip were kept in the finished movie — made it one of the best depictions of war ever created. I need to watch this movie again soon.
An incredible detail Puschak notes: the shot-length in that scene was surprisingly long, particularly for a battle scene. In fact, the shot length in that scene was more than double that of the entirety of 300, any Transformers movie, and Inception.
