HAHa you're right TIS!
That scene on the rooftops, there's this bit I really enjoy: As Vito is following Fanucci, there is a shot of Fanucci shoving through the crowd, and a cigar is protruding stiffly from between his teeth. I just laughed, he looked so pretentious, and seemed such an invulnerable bully boy, and he had no clue that this thin Sicilian peasant on the rooftop was going to blow his brains out. Just a funny shot. Look out for it!
