Burn After Reading (2008)

The lives of several characters intersect when the memoirs of a former CIA analyst, Osbourne Cox, accidentally fall into the hands of two clueless gym employees, Linda and Chad. Assuming they have classified information (perhaps a gold mine), the two blackmail the analyst, setting off a series of events involving the analyst's wife, Katie. This is a Coen Brothers-style film, with a parodic tone, which incorporates elements of action and espionage, and counts with a spectacular cast.
