ETA: Maddox mentioned Rob and 'Mission: Blacklist' in another interview with KGOU. You can listen the audio at the source, he talks about Rob at 13:25.
Here's a transcript of what he says:
GRILLOT: So I have to mention here, as we're finishing up, your book Mission: Blacklist is going to be made into a film. Robert Pattinson's been cast to play you in your movie. How do you feel about that? What are we going to learn? What are we going to see in this film?
MADDOX: I'm very excited about it. The one thing I've asked is that the movie be as real as possible. And working with Rob, that's the one thing he insists on. He always asks me, 'Is this real? Did this happen?' So it's exciting. We'll see.
