Access Hollywood released a new interview compilation from the Outlander FYC Event. Jolie Lash specifically asks Caitriona Balfe, Sam Heughan, Ronald D. Moore (loved that head nod) about Maria Doyle Kennedy who is playing Aunt Jocasta. Ron is also asked about the challenges of turning Scotland into America. He mentions that they shot in Slovakia to get the shots of larger rivers, which Scotland does not have. Maril Davis also touches on the Scotland to America transition as well as Rollo.
