The clip, released Wednesday, goes behind the scenes of the Bush presidency.
Rockwell's Bush is seen discussing with Bale's Cheney how he wants the former Secretary of Defense to become his vice president. Cheney then makes an agreement with Bush to allow him to handle bureaucracy, the military, energy and foreign policy despite having what he referred to as a symbolic job.
Vice, from director Adam McKay, is set to arrive in theaters on Christmas day.
Bale transformed himself for the role of Cheney, appearing to have gained a significant amount of weight to portray the politician.
