There is also a documentary about a timeshare property mogul building the one of the biggest/most expensive personal home ever, I believe costs were over $100 million.

Filming was in 2007, the 2008 financial crisis hit, and the documentary devolves into watching this mogul go bankrupt.

I remember a quote from the mogul, something like "I have nothing but the business. I've re-invested nearly every dollar I've ever earned."
