Back in September, Diana did an interview with Lightspeed Magazine. They discuss Outlander being turned into a television series and also some controversial scenes that will be brought to life in the show.
From Lightspeed Magazine:
But I mean, there are a lot of aspects of Outlander that are potentially controversial. Do you have any idea how those will be adapted for television?
Well, like Ron says, if it’s in the book, we’ll film it the way it is in the book. I couldn’t ask better than that.
