this isn't a new movie, but it's probably one of the better christian movies I've seen. http://www.amazon.com/exec/obidos/tg/detail/-/B00006K02D/qid=1101519058/sr=8-1/ref=pd_csp_1/102-4698386-6402568?v=glance&s=dvd&n=507846
It's a true story about a woman living in China at the time China was trying to destroy "religion". This woman becomes a christian and is tormented over it.
There are some really great scenes especally when she is put up against a firing squad.
