This fiendishly clever 'Doctor Who/Star Wars' mashup got posted over on FE.org recently and it struck me how Karen Gillan almost looks like a young Carrie Fisher at around the 02.12 mark in the clip (The hair, the Endor background and of course the Lightsaber all help).
Karen as Leia's daughter would be a great casting choice IMO.
^ Even found a photo of her with the ROTJ hair.
