Marlon Brando didn’t win the Academy Award in 1951 for his acting in “A Streetcar Named Desire.” The Oscar went to Humphrey Bogart, for “The African Queen.” But you could make a good case that no performance had more influence on modern film acting styles than Brando’s work as Stanley Kowalski, Tennessee Williams’ rough, smelly, sexually charged hero.
Before this role, there was usually a certain restraint in American movie performances. Actors would portray violent emotions, but you could always sense to some degree a certain modesty that prevented them from displaying their feelings in raw nakedness.
Brando held nothing back, and within a few years his was the style that dominated Hollywood movie acting. — Roger Ebert
