So I may be a bit late to the party on this one, but there are 2 *very interesting* parallels between Outlander and the Wizard of Oz (aside from the really obvious one in “The Gathering” (01×04)):
1. All the 1940s scenes are washed out, with muted colors. The moment Claire wakes up in 1743, we see lush greens and blues and real COLOR for the first time
2. Geillis wears red shoes. We see them close up twice – in “The Way Out” (01×03) and “The Devil’s Mark” (01×11)
So…no idea if this was intentional…but if it was: give credit where it’s due. Well played, Ron Moore.
