Bale joins a cast that already inclues Bradley Cooper, Jeremy Renner and Amy Adams . He was out, but now Christian Bale is back in David O. Russell's untitled ensemble drama. Bale , who earned a supporting Oscar in Russell's The Fighter , will join a cast that already includes Bradley Cooper, Jeremy Renner and Amy Adams . Russell wrote the screenplay with Eric Warren Singer, based on Singer’s original draft. The untitled project is based on the true story of a notorious financial con artist ( Bale ) and his mistress/partner in crime ( Adams ), who were forced to work with an out-of-control federal agent (Cooper) to turn the tables on other con artists, mobsters and politicians. At the center of the story is the passionate and volatile leader of the New Jersey state assembly ( Renner ) who is also the local hero and mayor of impoverished Camden. Bale was originally onboard to tackle the con artist role but dropped out in July. The film now marks a reunion of sorts
