And now, The History of Church Film Censorship!
The Hayes Code/Production Code answers are right, but there was also this:

It was founded by local dioceses as a response to the releases of Cecil B. DeMille’s “The Sign of the Cross” and somebody else’s “Ann Vickers,” the former contained pretty strong sexual content and and the latter touched on feminist-tinged sexuality.

They were indeed a functioning censorship body, and had the power to affect where a film could or could not play. They often took on films to review after the Production Code had signed off on them, and pronounced that “condemned” films could not be seen by Catholics as it would constitute a mortal sin. Here’s a complete list of films that the Legion “condemned”:

So they played a HUGE role in how the Church was portrayed in Hollywood productions of the day.
The list grows to include more foreign-produced films than American ones, as the Production Code was being enforced after 1934. Filmmakers such as the Spanish atheist and surrealist Luis Bunuel, who portrayed the Church in a not-very-positive light, would have had “condemned” films at that time.
In the 50s, courts ruled that religious bodies could not prevent the public from seeing films. Catholics who didn’t understand that the Legion warned people to stay away from certain films, not go and see them, were ignoring the Legion’s condemnations and going to see C-rated films anyway. By the late 60s even the Production Code was outdated as filmmakers began ignoring it completely and started intentionally violating the Code in the strongest possible ways, and the industry transitioned to the MPAA Rating System because of the threat of legislation from Congress. The Legion turned into a “recommendation” board and was finally dissolved in 1980.
Churches, especially Protestant clergy, continued to have censorship power in the South and other conservative states up until the mid - late 80s maybe. Major release films such as Jaws and Star Wars were cut and censored before distribution to theaters by the local church censorship boards. Monty Python’s “Life of Brian” was banned outright everywhere down south. Because of this, counties where the churches were actively censoring would receive films after the rest of the country did, and those prints were already wearing down. After playing the church-censored counties and doing their business, those cut prints would then go up to NYC’s ghettos where they would play in filthy, crime-ridden “grindhouse” theaters. Bad kids who were supposed to stay away would wonder why the film was jumping all over the place, later finding out after seeing it on video or HBO that it was because someone had cut sex scenes or whatever.
Then, the prints broke beyond repair. Or they would be sent to television stations for their film libraries. This is why some local TV airings of Hollywood films utilized absolutely dreadful prints.
According to “This Film is Not Yet Rated,” the documentary, priests and pastors do work with the MPAA’s ratings board, although they have no voting power. Liberal “open-minded” film buffs have decried this aspect as “the interference of religion in art!!! if they’re going to have priests they should have Satanists and Wiccans and Hindus and Muslims and Buddhists and!!!” even though the clergy obviously aren’t doing anything to stop the anti-Christian rhetoric coming out of Hollywood today. Go figure.
