Watching GF on Bravo tonight, the Corleone compound (mall?) that Clemenza and later Frankie take over, looks much bigger than it does in Pt II. In Pt II, when Frankie comes home and Michael is waiting for him, you can look across the street and see $5,000 houses (much like Hyman Roth's). In GF, all the surrounding houses are mansions. Any reason for this? I wonder if they shot that one scene in Florida on the same block as the Roth house?
