Fan Casting The Godfather Part IV (1999)

The fourth film was intended to be a prequel and a sequel. They had discussed a potential script, told in a similar narrative as Part II: with younger Vito Corleone and Sonny gaining the families' political power during the 1930s; and with Vincent Corleone in the 1980s, haunted by Mary's death, running the family business through a ten-year destructive war and eventually losing the families' respect and power, seeing one final scene with Michael Corleone before his death.
