[MysteriousWays]

France and Northern Italy, I think. Atlanto-Med + CM?

[Tooting Carmen]

France>Iberia>Italy. Atlantid verging on Atlanto-Med.

[teodor11]

Atlanto med.

She looks like caucasian/med girls

She can pass (half) North caucausia (circassia, abkhazia) maybe iberia.

[TheForeigner]

Her beauty and acting skills are overrated.

[The Blade]

bumping

[nafz]

She has been compared look wise to Natalie Portman. I think she also remotely resembles Brazilian Alessandra Ambrosio.

France, Iberia and Italy but she could pass in most if not all European countries.

[Sikeliot]

France.

[Oddone]

Excluding UK/Ireland, France.

[Inquizzzitor]

France. Totally France. But she actually could be "passable" anywhere from Serbia to Poland to Catalonia. A real pan-European look even if, knowing she is a Brit, she does actually have a British look.

EDIT: She doesn't look German, really. But I've even seen some dark-haired Swedes who have her look. She might even pass there.
