who did the dancing in saturday night fever
Saturday Night Fever is a 1977 American musical drama film directed by John Badham. It stars John Travolta as Tony Manero, a working-class young man who spends his weekends dancing and drinking at a local Brooklyn discothèque; Karen Gorney as Stephanie Mangano, his dance partner and eventual confidante; and Donna Pescow as Annette, Tony's former dance partner and would-be girlfriend. While in the disco, Tony is the champion dancer. His circle of friends and weekend dancing help him to cope with the harsh realities of his life: a dead-end job, clashes with his unsupportive and squabbling parents, racial tensions in the local community, and his general restlessness.
