Hear him speak in his real voice. It's a little startling. He discusses, among other things, how the scenes for "Borat" were planned and accomplished. The scenes had to advance the plot, but they could not be sure exactly what people would do and say. The scene in the church was pivotal, and the predicted dialogue turned out verbatim. With fundamentalists, it seems, you actually do know what they will say, for example, if you say, "No one can save me."
On many occasions, people called the police, and Cohen stayed in character as "Borat" even after the police arrived. You never know what useful footage you'll get. I guess we'll see that on the DVD.
Cohen thinks he's the victim of his own success, or so he says. He's so recognizable that he can no longer go out as a funny character and trick people. Or can he? He's saying now that he'll have to write scripted movies and work with actors, but that would be a useful message to send out if he wants to keep up the real-life tricks. He's awfully good at disappearing into his characters -- note that he studied acting and has performed in Shakespeare plays -- and, as he says, people consistently believed Borat was real. I think the tricks will go on, in some way or other.
