Stravinsky's "the rite of spring" was a seminal work in the history of music: it influenced a whole generation of composers who came afterwards. can you think of something, whether it be in movies, music, art, or anything else, that has had that kind of impact?

Marlon Brando's performance as Stanley Kowalski in Elia Kazan's "A Streetcar Named Desire", based on the play by Tennessee Williams, was the first example in film of an actor using the technique that would later be known as "Method Acting". Brando's performance influenced a whole generation of actors who wanted to emulate him, and "Method Acting" forever changed the art of film acting.
