looks like Mélanie Laurent from Inglorious Basterds

Yes, very similar but not quite as pretty--though could be because she's a bit older?. Close though.

Melanie who??

Yesh, I agree. She does bear a striking resemblance to Melanie Laurent. When I watched Beginners in the theaters a few years ago, I was thinking to myself, "Isn't that Jessalyn Gilsig?"
