ET Canada has a great segment on Outlander with interviews with the cast (Sam Heughan, Caitriona Balfe, and Tobias Menzies) along with Ron Moore and Diana Gabaldon. Other than the interviews, there are quite a few shots of things going on behind the scenes, most of it looking like it is taking place at Castle Leoch. The quality of the video is not that great, so screen captures are not worth much, but thank you to Outlander Italian Fans for posting this video. You Canadians can head over ET Canada and watch a better version of the video.
