Famke's Next Directing Effort: Adapting William Gaddis' 'JR'

According to E, Famke will adapt JR. Synopsis of the book:

J R tells the story of the eponymous J R Vansant, an 11-year-old schoolboy who obscures his identity through payphone calls and postal money orders in order to parlay penny stock holdings into a fortune on paper. The novel broadly satirizes what Gaddis called "the American dream turned inside out".

Seems like Famke is interested in exploring the American dream further after she touched on the subject in her first film.
