Goodfellas followed Henry Hill’s (Ray Liotta) rise and fall as a mob associate, starting when he ran errands for Paul Cicero (Paul Sorvino) and his crew when he was a teenager, along with a young Tommy DeVito, but did the real Henry Hill and Tommy DeSimone work together as teenagers? Based on the book Wiseguy by Nicholas Pileggi, Martin Scorsese’s Goodfellas tells the true story of mob associate Henry Hill, from becoming a close friend of Paulie, Jimmy “The Gent” Conway (Robert De Niro), and Tommy, to cooperating with the FBI as an informant, leading to the arrest of his former friends.
