What is "xica"

Xica is a 1976 Brazilian comedy film directed and written by Carlos Diegues, based on the novel by João Felício dos Santos, which is a romanticized retelling of the true story of Chica da Silva, an 18th-century African slave in Brazil, who attracts the attention of a powerful Portuguese land-owner and eventually rises into the Brazilian high society. The movie stars Zezé Motta, Walmor Chagas and José Wilker. It was chosen as the Brazilian submission for the Academy Award for Best Foreign Language Film at the 49th Academy Awards, but it failed to get a nomination.
