Marlon Brando revolutionized film acting by bringing method acting from theater to Hollywood. His naturalistic style in "A Streetcar Named Desire" and "On the Waterfront" changed what was possible in film performance. His portrayal of Don Vito Corleone in "The Godfather" remains one of cinema's most iconic performances. Brando's influence on subsequent actors cannot be overstated – nearly every major actor since has cited him as an inspiration. His rebellious persona off-screen matched his revolutionary approach to acting. Despite later career controversies, his artistic legacy remains untouchable.
