On Argo: "Yeah. A lot of the forces that are coming to bear on our hero and on everyone are invisible. There's not one antagonist in the film, it's a widely distributed sense of threat that's out there. It's sort of a big geopolitical problem that they're up against, in a sense.
Since you can't throw invisible stones at characters, you have to begin to create stones that have weight and that have sharp edges and that feel credible. So that's in a way how the story developed, just to get a sense of the various ticking clocks and the various sorts of obstacles hanging above the heads of the characters.
And then the next problem is how do you reconcile the three tonal worlds of the film – the world of Washington and its bureaucracy; the world of Tehran and the immediate sort of clear and present danger of the guards that are combing the city with automatic weapons; and then the world of Hollywood where the challenge really is to create a convincing fiction, or film? The problem becomes how do you write a script in which those three things are the same movie, and in which the tone feels like it carries over from one scene to another?
Some of it is just trial and error. You don't want the characters in Hollywood – Lester Siegel and John Chambers – to turn into kind of a Vaudevillian sideshow. You want to feel that they're human beings who are deeply invested in the lives of other human beings who are the six houseguests.
You want to feel that in the world of the CIA, it's a deadly serious world of an espionage thriller, but also Bryan Cranston and his character has an acerbic sense of humor, so you could imagine him meeting up with Lester and with Chambers and sort of having the same conversation.
And then further, with the houseguests in Tehran, you have these six people who are in this is Jean-Paul Sartre, No Exit kind of situation where they're stuck in the house, but you also want to feel that the way that they talk and the way that they relate to each other can cut from Hollywood or from Washington to them and still feel like you're watching characters in the same movie. I'm not sure that I did solve all these problems, but you write the script and hope for the best."
I think Chris did a great job of "juggling" characters in Argo. I think he should heavily influence the JL movie. So if there are a lot of characters, I think he'll try to give them all a sort of weight.
