I just came across this trailer for a movie called "Defiance". It's scheduled for release this December. It stars Daniel Craig (the new James Bond guy) as a Jewish Russian partisan. Don't know much else about it except for the blurb up on the Apple movie trailer website.
They say it's "based" on a true story.
Here's the official blurb:
"In WWII Russia, Jewish refugees band together into a brigade that hides in the forest, ambushes Germans and survives until war’s end, eventually 1200 strong."
