I think Castello wanted his girlfriend to write his dialouge.
Yes. Harlan Lebo quotes FFC saying that money wasn't the issue. Castellano wanted "his associate" (actually his girlfriend, Ardell Sheridan, who played Mrs. Clemenza in GF) to write dialog.
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.
