14. Nicolas Cage
At the peak of his legendarily eccentric spending spree, right alongside the castles, the dinosaur skull, and the haunted New Orleans mansion, Nicolas Cage picked up his own island in the Bahamas. He bought Leaf Cay in the Exumas in 2006 for an estimated $8.5 million, drawn to its untouched beaches and deepwater access for yachts. He never developed the 14-acre property, partly because it is home to endangered Bahamian rock iguanas, and later listed it for $7.5 million while resolving tax debts. | © Relativity Media
