3. Boogie Nights (1997)
The 1970s go out with a bang—literally—in Paul Thomas Anderson's epic ode to porn. The dawn of a new decade means new beginnings for all of the film's 624 main characters, with hints of what's to come for each of them seen throughout this 15-minute sequence (including budding drug addictions, business ventures, romantic entanglements, and the birth of videotape).
But the sex, drugs, and rock 'n' roll lifestyle prove too much for assistant director Little Bill (William H. Macy), who decides to bow out of the next decade when one too many adulterous walk-ins on his wife lead him to shoot her, her lover, and himself at a crowded party as the clock strikes midnight.
