She looks like Julianna Marguiles

No! She doesn't look like Julianne at all or resemble her.

White and brown hair?

They don't really look alike but I can see some similarities. I didn't know Siff was 40... she looks much much younger.

Completely agree; came on the message boards to find out if any one else has noticed!

yes, she does, without being in danger of being mistaken for her, there is some kind of common-CATEGORY to their look and ambience..

Both are Eastern Jews, anyway, I understand, maybe it is ethno-centric...both are compelling and sultry without being the prettiest girl in the club.

Margulies and Famke Jansen from 'Taken" also have a lot of overlap.

No, not really.

she does not look like her exactly, but there IS some kind of commonality there..

both that poster and I think of Margulies when we look at Siff..

Both-sultry. SULTRY!
