In page Roberto Calvi:

BBC One's programme Panorama chronicled Calvi's last days and uncovered new evidence which suggested that others had been involved in his death.[1] The 1983 PBS Frontline documentary "God's Banker" investigated Calvi's links with the Vatican and P2, and questioned whether his death was really a suicide.[citation needed] The circumstances surrounding his death were made into the feature film I Banchieri di Dio - Il Caso Calvi (God's Bankers - The Calvi Case) in 2001.[2] A heavily fictionalized version of Calvi appears in The Godfather Part III in the character of Frederick Keinszig.[citation needed]
