4. Within a Minute: The Making of Episode III
Within a Minute runs down the production of Revenge of the Sith, with a specific focus on the climactic, minute-long lightsaber duel between Anakin Skywalker (Hayden Christensen) and Obi-Wan Kenobi (Ewan McGregor).
More than anything else, this doc exhaustively details the mind-boggling amount of people and man-hours required to produce even a mere 60 seconds of blockbuster film, covering everything from the most mundane logistical minutia of feeding the cast and crew to the top-level creative decisions made by George Lucas himself.
And despite dedicating almost 80 minutes to a single short sequence from the film, Within a Minute's revelations hold true for the movie as a whole - if not most of the prequel trilogy also.
For anyone interested in the guts of filmmaking and how almost unfathomably huge movies are produced, this is an excellent starting point, given how concisely it examines the process from the ground-up.
