David Fincher, whose latest movie The Social Network opens October 1, is a master of form; there's usually a reason behind every shot and cut in his movies—a big-picture sensibility that explains every choice. That includes credit sequences, an aspect of Fincher's filmmaking that's examined in this five-part series of video essays. From the brazenly spectacular sequences that open Se7en and Fight Club to the more sedate, elegant openings of Alien³, Panic Room, and Zodiac, Fincher cements his reputation as a big-budget utility infielder, trying his hand at many different genres, but always letting the story dictate how he tells it. Part 1 examines Alien³, Part 3 Fight Club, and Part 4 Zodiac. Part 5 will examine the The Social Network.
