What is Classical Hollywood Narration?

In this video, I introduce the basic principles of "classical Hollywood narration," a set of storytelling conventions established during the classical Hollywood era (studio-produced American cinema roughly between the 1910s and the 1960s). This video looks at Rear Window (Hitchcock, 1954), a film produced during the classical era, and Gravity (Cuaron, 2013), a film produced after the classical era but which embodies these principles.
