FILMS SAY AMEN TO RELIGION
In the summer blockbuster movie "Mr. and Mrs. Smith," Brad Pitt and Angelina Jolie play godless suburbanites and professional assassins. But when they steal their neighbor's car, a crucifix hangs conspicuously from the rear-view mirror, and in the next scene the actors wear borrowed jackets that read "Jesus Rocks."

I read the whole article and I reached the conclusion that using religion in movies is another "Hollywood fashion style". Even though there are lots of Christian producers and sponsors who try their best to stop profanity in scripts, based on a study, Christian people are more likely to watch R rated movies for violence.
