De Palma
It was De Palma who introduced Scorsese to the young actor Robert De Niro. De Niro had known De Palma for several years previously, and his first film role in collaboration with De Palma materialized in 1963 at the age of 20, when he appeared in "The Wedding Party". However, the film was not released until 1969. The two reunited for the 1968 film "Greetings", which was De Niro's official film debut.
