Although Flor Silvestre had made her film debut in 1949 singing in Te besaré en la boca (released in 1950), she was given her first leading role in the Walerstein production Primero soy mexicano (1950), co-starring Joaquín Pardavé (who also wrote and directed the film) and Luis Aguilar and featuring Francisco "Charro" Avitia. She was reunited with her Primero soy mexicano co-stars Luis Aguilar and Francisco Avitia in the film El tigre enmascarado, which premiered in 1951. She then appeared as the leading lady of actor Dagoberto Rodríguez in a film trilogy, El lobo solitario, La justicia del lobo, and Vuelve el lobo (all released in 1952). 1955–1957: Return to films and television debut In early 1955, Flor Silvestre sang on the XEW radio program Su programa Calmex, sponsored by Calmex Sardines.
