The American Dream is a beautiful thing, unless you build your empire on the back of a bubble only to have that bubble burst. So goes the rise and fall of the Siegel family, captured by documentary director Lauren Greenfield in The Queen of Versailles. Billionaire David Siegel and his wife Jackie (30 years his junior) built a 90,000 square foot mansion upon the shifting sands of the real estate market. When that market collapsed, the Siegels were in the same boat as the rest of us (more or less). The new trailer evokes a few laughs, a heap of frustration and just the slightest whisper of sympathy. Hit the jump to check it out, along with a poster featuring Mrs. Siegel and the monstrous $100 million mansion. The Queen of Versailles opens July 20th.
