From a new article in the Washington Post:
Norquist, the president of Washington-based Americans for Tax Reform, first shot an office scene, handing a three-ring binder to heroine Dagny Taggart’s assistant. Easy enough, it sounds. Then producers suggested a second role. For a scene where Dagny and Hank Rearden walked along the street discussing the decline of society, they put Norquist in the background as some kind of down-and-out businessman, slumped on a stone bench, a bottle of wine in his lap. They roughed up his face with makeup, and messed up his hair, but he wore his own suit.
The actor playing Hank commended Norquist’s acting ability — he even stayed in character between takes! Consider it his Method approach: Having woken up 20 hours earlier for his West Coast flight, Norquist was nodding off by the time of the night shoot. “I’m half asleep, my character’s half asleep,” he said.
