For those of us too young to remember ABSCAM, that's why we have people like David O. Russell. ABSCAM was a sting operation in the 70's and 80's originally set to recover stolen property which ended up targeting corrupt public officials.
The operation brought together a wild cast of characters, including con men, women of ill repute, and general bon vivants that very well could have been in jail were they not helping the U.S. government. In addition to serving justice, it served as a pretty great reason to get these miscreants together to party.
The trailer features Christian Bale, Jeremy Renner, Jennifer Lawrence, and Bradley Cooper filling out these roles nicely (and with some epic late-70's hair).
