Tango Feroz (1993)
Tango Feroz: la leyenda de Tanguito is a 1993 Argentine movie blockbuster, freely based in the life of Tanguito, one of the first artists of Argentine rock ("Tanguito" is just a stage name, nor the artist or the movie are related with Tango music). Fernan Mirás and Cecilia Dopazo, unknown by the main public by that point, had the lead roles and became famous after the movie, directed by Marcelo Piñeyro. It was the most successful movie in Argentina at the year of its release.
