CleanFlix directed by Andrew James and Joshua Ligairi [February 2010]
In the 1980s, Mormon prophet and LDS church president Ezra Taft Benson famously counseled the young men of his church to avoid watching R-rated films:
Consider carefully the words of the prophet Alma to his errant son, Corianton, “Forsake your sins, and go no more after the lusts of your eyes.” 
“The lusts of your eyes.” In our day, what does that expression mean?
Movies, television programs, and video recordings that are both suggestive and lewd . . .
We counsel you, young men, not to pollute your minds with such degrading matter, for the mind through which this filth passes is never the same afterwards. Don’t see R-rated movies or vulgar videos or participate in any entertainment that is immoral, suggestive, or pornographic. 
Though his words were directed at young men specifically, in practice, they became applied to church members in general. So began the cultural Mormon phenomenon of shunning R-rated films, in America, at least. Mormons would be far from the only religious conservatives to take issue with the graphic content of modern-day films based on MPAA ratings.
