Politicians and the media like to talk about the relationship between Wall Street and Main Street, but investigative journalist Leslie Cockburn’s debut feature gets to the guts of the matter, visiting defectors from Bear Stearns and Standard and Poor’s and other high-level players in the subprime mortgage gamble and, on the flipside, visiting the working-class Americans who were the unwitting chips on the table. Screening at the 2009 Tribeca Film Festival. For more information and tickets, visit www.tribecafilm.com/festival.
