I was struck the other day by how much actress Katrina Law (Nyssa, Arrow) reminds me of Julia Ormond when she was one of Hollywood's "It" girls. It's not just looks, it's also the light British accent she carries. She does have an Asian influence on her physiognomy, but there's definitely a resemblance.
(BTW, Arrow hinted at a possible girl-girl relationship between Nyssa and Laurel. I wonder.)
So, compare: Julia above, Katrina below.
