http://www.jgeoff.com/scarface/sf_notes.txt The second home -- seen as Tony's Coral Gables mansion -- has an even more exotic history. The work of Bertram Goodhue, it was conceived in 1906 as a steel and concrete version of a neo-classic Roman villa -- containing one vast bedroom (which various owners would later remodel to suit their whims and needs) -- on a 35-acre plot.
Its original owner was a gentleman named Gillespie, whose other properties ironically included the palace in Havana which Castro later assumed as his headquarters.
Among the features of the estate were an artesian water system which fed a network of lagoons and lakes, one of which boasted an Egyptian barge for private parties, and the world's largest collection of palm trees, many of which were transplanted in the early 1950s to become the "Jungle Ride" at Disneyland.
Previous residents included author Thomas Mann, who entertained such house-guests there as Albert Einstein and Winston Churchill. And when director De Palma staged the wedding of Tony and Elvira on the lavish grounds, he could refer to a previous, equally celebrated ceremony on the same site, in which Charlie Chaplin and Oona O'Neill were united.<<
