Adam McKay, director of a coming film about the life of Vice President Dick Cheney, tentatively titled Cheney, said Ms. Adams and Christian Bale a reputed method actor and her previous acting partner in The Fighter and American Hustle showed similar devotion to their characters.
Mr. McKay said Ms. Adamss fluid portrayal of the second lady Lynne Cheney, which in the film covers five decades, resulted in a kind of uncanny hybrid that he and the rest of the crew took to calling Amy Cheney.
Shes talking in that voice and emotionally leaning in that direction, he said. But you can still call her Amy and joke around and talk about other things.
Occasionally, the Cheney persona political ideology and all manifested at surprising moments, like on the day Congress passed a sweeping overhaul of the tax code.
Mr. McKay had found the news depressing, believing the bill favored the superrich, and, speaking to Ms. Adams about it on set, was taken aback when she all but accused him of being a socialist.
She looks at me, totally in character, and immediately goes, Well Adam, when people do well in life, they shouldnt be punished.
