In other words, Republican Vinick, played by Alan Alda, and Democrat Santos, portrayed by Jimmy Smits, will listen and respond to each other — as opposed to real-world debates that tend to excise substance or spontaneity.
The fictional encounter starts with the usual rules, the kind that "are set up by the candidates and are there to protect the candidates and not promote an informed debate," said executive producer Alex Graves, who is directing O'Donnell's script.
But one of the politicians — Graves won't say who — quickly proposes tossing the book aside.
"And that's the starting point and everybody, including the moderator, underestimates what that's going to mean," Graves said. "It ends up ... with the candidates doing and saying things you would never expect to see in a debate, never."
The actors may also do something rarely seen. Although they have a script, Alda and Smits also received a crash course in debate strategy and issues that will allow them to veer off the page.
