The creators cast Ted Danson for the part of Arthur Frobisher, a corrupt billionaire CEO, because of his role in "The Onion Field" (1979). Danson was attracted to the project immediately after learning that Close would be playing the lead role. As part of his preparation, Danson studied the collapse of Enron by watching documentaries such as "The Smartest Guys in the Room" (2005) and meeting CEOs of various Fortune 500 corporations. The producers also suggested that Danson consult Close's acting coach Harold Guskin. Danson was initially hesitant about this suggestion, but found the consultation extremely helpful.
