Once Upon a Time in Wonderland

Intrigued. When they first announced this, I thought it would be stupid (Considering I think Once Upon a Time is stupid, yet still watch....) but this trailer actually looks interesting. Hoping that Rose McGowan or Barbara Hershey reprise their roles as Cora, but it doesn't appear so based on this trailer. (That actress we get a glimpse of isn't either of them, is it?)

A lot of 'Return to Oz' undertones, no?
