Míriam Colon started her acting career appearing largely in Westerns. Though some of her characters recurred regularly, she played a variety of different parts on the Western television drama "Gunsmoke". She also appeared in two Western films with Marlon Brando. In the first, "One-Eyed Jacks", Colon had a very minor part, though the film was more notable because Brando directed and starred. In the second film, "The Appaloosa", Colon had a slightly larger role as a childhood friend of Brando's character. In the biopic "A Life of Sin", co-starring Raul Julia, Colon took the starring role as notorious Puerto Rican madam and brothel owner Isabel la Negra--a legendary figure in Puerto Rico's folk history. One of Colon's more high-profile projects in the latter half of her career include crime epic "Scarface", in which she was Mama Montana, mother of Cuban gangster Tony Montana, played in an iconic performance by Al Pacino. In the 2000s, Colon had a costarring role in the "Goal!" trilogy of movies, which follow the life and career of a working class Mexican-American who becomes a professional soccer player. Colon plays his encouraging grandmother. In addition to Colon's longevity in the television and film industries, she is the founder of the Puerto Rican Traveling Theater in New York City, in which she also acts.
