Thirty years ago, audiences of all ages embraced a disco flick with dark undertones, earning Saturday Night Fever a permanent place in pop culture. The iconic seventies film that helped define the look and sound of a generation is often remembered for its polyester-and-platform dance scenes at a club called "2001 Odyssey." There, a young Tony Manero, played brilliantly by John Travolta, reigned as king of the dance floor. But beyond the mirrored balls and catchy Bee Gees tunes, there were serious subject matters such as teen pregnancy, suicide and the working-class struggles of some Brooklyn-born Italian kids. Featuring interviews with key players and music from the unforgettable soundtrack by the Bee Gees, this two-hour special looks at the film that captured the disco era and shot John Travolta from sitcom star to pop culture icon.
