To be honest, one of the things that sticks out to me about a good movie is the theme of redemption. I love it, because whether the atheist film maker realizes it or not he is paying homage to God by realizing that things are wrong and need to be made right, even if at times that redemption takes a secularized form.
Let me give you a good example of a movie that really pays homage to Christianity (and even Calvinism) whether or not the directors and writers (in this case, the same people) intended it: The Matrix
-Neo is "chosen" by Morpheus, when he thinks he's the one doing the choosing
-Neo comes to realize that all this time he has been living in slavery in an evil and maligned system, of which he was a part without consciously realizing it (How many people have you run into whom you have confronted as being sinners, and they inisist your label should be on somebody else who is worse than they are?)
-It is only through Morpheus and the resistance fighters that Neo is able to break free from the Matrix, and even after that, he is dependent upon them to recover from his "dead" state.
-It is through the resistance that Neo learns who he is, and how to handle himself accordingly.
-Neo, once released, thus returns to the world of the Matrix, but no longer as a "part of the system" (in the world, not of the world)
And on it goes.
Yes, I realize that The Wachowski brothers are probably not Christians, and may not even be deists. Yes, I realize there's profanity and taking of God's name in vain in the movie-you run into that everywhere you go in the real world (sometimes in the church unfortunately). But the point is that, whether they realize it or not, they are communicating ideas and truths of Scripture without realizing it. They're unconsciously bearing the image of their (and our) Creator, even if they reject Him.
