Saturday Night Fever (1977)

The movie which single-handedly made disco the dominant force on the planet for a brief period of the 70s and launched John Travolta to stardom. 

It also changed disco from the elite pastime of a few drug-crazed Americans with liberal views on sex into a global pastime for all the family. And it gave punk something else not to sound like . . .

Tony Manero was the disco-dancing young Brooklynite brought to heel by the love of a good girl (Karen Lynn Gomey).

Saturday Night Fever owed its success to more than the expert marketing of its star-studded soundtrack.

Under John Badham's tight direction it emerged as an engrossing study of the rites of passage of the working-class American male - Tony's routine life during the day is transcended by his stunning skill on the dance floor at night.
