Don't ever expect another explicity pro-Christian movie from Hollywood. Afterall, Gibson got no support from them for "The Passion."
Any movies that have pro-Christian themes will be in the mold of "Lord of the Rings", where its not so explicit that it can't be denied.
I heard that the original plan for the Narnia movie was to remove all the "Christian elements" from it to make it more "mainstream", but that plan was scrapped. Hollywood believes in the worship of self and nothing else.
