Hence the profusion of sightings of James' rear end.
“There wasn’t enough nudity,” James jokes on the latest episode of EW’sScreen After Readingpodcast.
“No, it’s a part of the DNA of the book.
What I liked about it is the nudity is dangerous.
He’s thrown out of time, and it expends a lot of energy.
It’s an affliction, an illness that he has to deal with.
Nothing to protect himself with.
Nothing to help himself with.
It’s something that he has to overcome or survive over time.”
“Audrey’s version of time travel, you have to understand the rules,” Moffat says.
It only happens once.
Today’s what you’ve got.
Right now is what you’ve got.
He’s naked, he’s running, it makes him vomit.
It’s not Doctor Who popping out of the police box, is it?"
