Like Rosario Granados and Marga López before her, she was an Argentine entertainer who was relatively unknown in her homeland but became a major Golden Age movie star in Mexico. Libertad Lamarque was already a huge star in Argentina by the time she came to Mexico.
In 1988, she said her favorite male co-star was Pedro Infante because he was "so cheerful, so willing to joke around". They starred in the film El mil amores (1954).
