Nicholas Pileggi's book, "Wiseguy," is basically Henry Hill's biography. As far as I know, everyone in the movie was based on a real character. Only Henry and Karen kept their real-life names; the others had their names slightly changed for the film.
Ntra la porta tua lu sangu � sparsu, E nun me mporta si ce muoru accisu... E s'iddu muoru e vaju mparadisu Si nun ce truovo a ttia, mancu ce trasu.
