Watch Full Movie Online. The mythical Uruguayan version of Saturday Night Fever, directed by J. Eduardo Ribero (yes, the one from Karibe with K), Sábado Disco Sábado Pachanga tells the story of a humble boy with a dream: to win the dance trophy. Faced with this desire, a businessman who will do everything to avoid his triumph takes precedence. With music by Rada, Psiglo and Diane Denoir, Sábado Disco is a film as disconcerting as it is unforgettable.
