by that logic Gal could play her (cuz she also spoke hebrew)

but would make more sense for this historical drama, to make it more realistic which is what you aim for in this genre, to look for some actress with a greek background as that is where her main heritage is from

so maybe a new talent for this part, and other roles, i'd suggest Ben Kingsley would be a good one in this too, given he already had some experience with historical figures
