@Sven - The car in TMWTGG is a working model, I believe. It really is a flying car. But we're in the land where assassins kill with a golden bullet fired from a handgun, the Thai government lets a wanted criminal have an entire island, and someone as hot as Britt Ekland actually exists. Logic doesn't apply here.
Actually china owned scaramanga's island, he did a few jobs for them now and then as rent.
That I find completely real;istic.
