Vivien Leigh- Perhaps the MOST remembered of Marlon's costars, Vivien Leigh starred alongside him in A Streetcar Named Desire as Blanche DuBois. Together, they made movie history, Vivien's second time (She starred as Scarlett O'Hara in Gone With the Wind!) and Marlon's first of many!

Karl Malden- Karl and Marlon remained close friends throughout their lives. He starred in several movies with Marlon including Streetcar, On the Waterfront, and One Eyed Jacks. Another notable film of Karl's was the famous Patton, with George C. Scott.

Eva Marie Saint- Marlon and Eva starred together in the incredible movie On the Waterfront, for which Marlon won an Oscar. Eva Marie went on to do great things as an actress, and Marlon as an actor, as we all well know!

Montgomery Clift- Montgomery Clift was perhaps the only actor that I feel you can truly compare to Marlon. Together they starred in The Young Lions, and remained friends. Although Marlon tried to get Monty to stop drinking, it was alcoholism that eventually caused his death. Clift starred in notable films such as I Confess (with Karl Malden), The Heiress (Olivia de Havilland), and From Here to Eternity. One of the greatest actors ever.

Al Pacino- Al Pacino starred with Brando as Michael Corleone in The Godfather. The Godfather gave Brando one of the most remarkable movie comebacks EVER. Al Pacino went on to do great things in notable films such as Dog Day Afternoon, The Devil's Advocate, and more great movies. Pacino much prefers the stage though, and is a true actor's actor.

James Caan- James Caan also starred in The Godfather. He also went on to do some wonderful movies. Of course, at the moment I can not remember any of them!

Robert Duvall- Again, Duvall starred in The Godfather. He went on to become one of the greatest actors of his generation. He went on to star in several wonderful movies, including one in 1997 which he wrote and directed himself. Name coming soon!

That's all for now! I'm going to go find some more people to put here!
