(On how Captain Jack is slowly become a little more like The Doctor in "Doctor Who")
John: There's tons of stuff there to develop now, all around Jack. It's a huge science fiction world we're creating, and all the time Jack is getting more like the Doctor – with all this history, and his assistants around him. I was thinking about it the other day, and it was a really cool revelation! I had a great big grin on my face for the rest of the day.
