25 best party movies ever

Boogie Nights (1997)

Paul Thomas Anderson's Oscar-winning yarn about the ‘70s porn industry is a paean to decadent disco-era revelry. And a party is one of the pivotal scenes – a bash on New Year’s Eve 1979 heralds the arrival of the darker, more tragic 1980s when Little Bill shoots his adulterous wife, her lover and then himself. It's all downhill from there.
