Godfather 2, The Easter Egg - Director's Daughter

In the scene where the young Vito Andolini (soon to be Vito Corleone) is on the ship to America, Sophia Copolla, the director's daughter, is one of the little girls on the deck near Vito.

Sophia Copolla appears in all three Godfathers. In the first she is Michael's infant godson who is being christened and in the third she plays Michael Corleone's daughter.
