The 2012 movie
Snow White and the Huntsman unexpectedly asserted many ancient themes, and first among them was the power of innocence. Within the film, innocence brings with it faith, hope, and charity. Two other Christian themes include the power of evil coming from subversion of good and the redemption of the fallen. Although there is almost no visual Christian presence in the movie, no crosses or other symbols, Snow White does recite the Lord's Prayer early on, which I think shows the writer and / or director were aware of some or all of these themes.
Medieval themes include birds as messengers, the power of blood, the dark and dangerous forest, the importance of a virtuous ruler for the natural phenomenon of a kingdom, and chaste love. That last is also a Christian theme, but here it seemed more medieval in expression to me.
And, of course, the story of Snow White is about the nature of Beauty.
The images of Snow White-as-war-leader in the movie are reminiscent of Joan of Arc. With a quick search, this was the best I could find of Snow White:
Here are two images of Joan of Arc from the website
Catholic Saint Medals.
Another aspect of the movie is that, while she does wear armor and fight, she is not shown as a great warrior. Rather, she is portrayed as a natural leader: Broken, hopeless warriors who have turned to drunkenness, outlawry, or despair, are redeemed by her innocence and her sense of the mission of redeeming their land and people. With her, they are given new hope and faith. She leads, and with the tremendous power of hope and faithfulness she brings, they fight and die to restore their land and themselves.
