I think that the mansion is a copy of a villa by Antoni Gaudi, the famous Spanish architect who designed numerous buildings in Barcelona along those lines.
G. White kindly wrote in to add: Yes, the house is definitely a Gaudi-inspired masterpiece, incorporating all the Art Nouveau-ish swirling patterns -- not a straight line in the whole compound. Gaudi was a tremendously important influence on architecture and design, mostly in Europe. America seems to have largely ignored him. There is a lot on Gaudi and his work on the Web, and particularly a very well-known cathedral ... in Barcelona, IIRC. Andy Garcia's character mentions Gaudi as he is showing Jeff Bridges around the place.
