Director Martin Scorsese admits that Goodfellas' most iconic scene was not originally scripted. Starring Ray Liotta, Robert De Niro, and Joe Pesci, Goodfellas is the story of Henry Hill's life with the mafia. The 1990 gangster movie is considered one of Scorsese's best films, which was nominated for six Academy Awards. The film has stood the test of time to be considered a classic, outshining Scorsese's other gangster-centric films, like Casino and The Irishman.
