marlon brando was one of the biggest stars of the 1950s, and he made a significant contribution to the film industry. he starred in numerous iconic films such as a streetcar named desire (1951) and on the waterfront (1954), and was one of the first actors to use method acting techniques to give a more realistic and powerful performance. he also wildly popularized the "rebel" or anti-hero archetype in film, paving the way for actors like james dean.
