Amazing Grace, which just came out, is suppose to be a great movie for Christians and conservatives. Patricia Heaton ("Everybody Loves Raymond") is one of the producers and she's a pro life conservative.
I have also heard it is a very good movie. Probably watch it when it comes out on DVD. But Patricia Heaton and others like her are probably 0.1% of the folks in Hollywood - very bad odds for a corrupt industry that has so much influence on America and even the world.
