Yeah, no kidding. He commissioned most of the ship models, including aircraft carriers with aircraft! I'm thinking $90,000 to $120,000 for the basement and theater without the decorations.

I've wondered if a 747 main deck interior nose section could be used to build out a home theater. It would be a cool concept, but it would require framing out the fuselage side mounts, which depending on how you built the offsets could be a pain.
