“Gross delights in telling inside stories about the gaudy world of master-of-the-universe apartments,” Max Gross (no relation) writes in an article in today’s New York Post on Alex Gibney’s “Park Avenue” documentary, based on 740 Park. The Post also sneaks the name of the worst tipper at 740 Park, which is revealed in Gibney’s film. UPDATE: Business Insider give Gibney’s trailer some linkage love.
