Robert De Niro as Abraham
Abraham was history's original Godfather. He wasn't so much a simple shepherd as a wandering heavy, battling with local warlords, and occasionally rescuing his brother, Lot, from the clutches of nearby kings. He was duplicitous enough to twice offer his wife to powerful leaders, but still favored by God, who blessed him with countless nations--most of which are, strangely enough, also now at war. Who but De Niro could play this guy?
