When Michael goes back to the states, the Corleone's financial resources seek him out and find him and kill him.
There is also a great scene where the under taker, whom we saw in the original as just a humble, frustrated man who begs Don Corleone to kill the men who raped his daughter and got away with it, reveal himself to be just the opposite. He is a constant complainer and is horribly ungrateful. We never would have seen that in the uncut version.
To end, this edited for television version that combines parts 1 and 2 is such a joy to watch because of the superb story telling that weaves the two tales together masterfully.
