Oy, that's a tough one.
Passion of the Christ (2004)
I know, that's an easy answer, but I think it's easy because it's one of the only movie depictions that seemed to get it right.
Father Brown (1954)
This movie is based on the book series by G.K. Chesterton, who was a major influence on C.S. Lewis's conversion. The story is about a priest who has an intuitive sense which he credits to God and often works privately as a detective in order to try and help rectify a right from wrong, but even more interestingly, to try and save the soul of the criminal. Alec Guinness played the role of Fr. Brown and did a great job.
Remember the Titans (2000)
I hesitated in listing this one originally. I was going to say it is indirectly a Christian-themed movie, but the more I think about it, I think it is directly one. It points to trusting in God to overcome obstacles, to shut down your own pride, do what is right toward your own friend, but even better, forgive your enemies. Really good movie.
The Mission (1986)
This is one of my favorite movies. It is about a conquistador who once worked in enslaving the Guarani Indians who became overwhelmed in God's love, became a priest, and worked toward saving them to his own death. Also, it was the most beautiful film scores in history (in my opinion).
The Buttercream Gang (1992)
If you were a homeschooled kid from the early to mid-90s, you probably saw this movie a million times. While sort of cheap in production, the story is incredible. A group of young teenage boys had a club in their town called the Buttercream Gang, where they went around helping people anyway they could. One of them goes off to Chicago to help with his widowed aunt but is kicked out after he gets himself into trouble over and over again. Back in his town, he continues to cause trouble doing the opposite of what he used to do. But the story gets especially interesting as it gets heavily into the teaching of turning the other cheek, forgiveness, and loving your enemies unconditionally even when it seems impossible. Best of all, it illustrates that just because it's right, it may hurt.
The Lord of the Rings trilogy (2000s)
For some, this is very obvious. For others, they will argue that this is perversion to the Christian faith because of characters like Gandalf. However, if you read Tolkien's commentary on Lord of the Rings, he doesn't just point out that it's some sort of allegory (actually, he was said to have not been a fan of allegories which is why he didn't like the Narnia books), but he goes into the Christian aspects of it in an accurate way. I couldn't not list this.
The Lion the Witch and the Wardrobe (1988).
OK, so I'm listening to BBC version because I enjoyed it more. And this is easy enough.
