One of the special features on upcoming home release of Outlander season two is about the Claire and Jamie’s Parisian apartment as well as Versailles. For some reason, I thought the courtyard was a location, but it is actually in the Outlander studio. This featurette has interviews with Ronald D. Moore, Jon Gary Steele, Gina Cromwell, John Casey (Property Master), Caitriona Balfe, and Lionel Lingelser.
