The project reunites award-winning director and co-writer Adam McKay with Christian Bale and Steve Carell, as well as Amy Adams. Bale will be headlining as former Vice President Dick Cheney, with Adams as his wife Lynne Cheney, Sam Rockwell as George W. Bush, Carell as Secretary of Defense Donald Rumsfeld, Tyler Perry as Colin Powell, and Bill Pullman as former Vice President Nelson Rockefeller. Cheney is regarded as one of the most powerful and influential U.S. Vice Presidents in history, having served under (and, as many regard, OVER) George W. Bush from 2001 to 2009. The former Halliburton chairman/CEO - who also served in the Richard Nixon, Gerald Ford, and George H.W. Bush administrations - was a hawkish proponent of the War on Terror and the Iraq War, and eventually left office with a 13% approval rating.
