The BBC confirmed his death Monday, but did not report a specific cause of it.
Favio's film credits include "Nazarene Cross and the Wolf," "Peron, sinfonia del sentimiento" and "Aniceto." He also had a number of hit songs in Latin America in the 1960s and '70s, including "She Already Forgot Me," "You Were Mine One Summer" and "Or Perhaps I'll Just Give Her a Rose."
Favio was appointed Argentina's ambassador of culture two years ago, the BBC said.
