Era of profanity in movie scripts?

There was no movie rating system in place back in the 1940's, and movies were greatly censored by the US government. In the 1920's the Supreme Court ruled that free speech did not apply to movies, and a control board was arranged where by all film studios had to submit their scripts for censorship.

Movie studios were given guide lines by which they had to follow. So it's not so much that profanity is now widespread, as much as it was strictly forbidden back in the 1940's.

This system of governed film making slowly started to collapse over the years and gave birth to the Motion Picture film rating system. Where the film ratings and censorship is controlled by the film industry and not by a single controlling person or government.

Now that we have the rating system, films can be classified by their rating. Today's ratings are, at least by idea, implemented by our peers. So as society changes so do those who review and rate films.

That is why we see more profanity in PG rated films, as parents who rate the films accept the fact that children in this age group use these profane words or acknowledge that the film works the way the script was written.

New ratings were introduced including PG-13. To address the need for films that target a segment of the population that are pre-adult but seek adult style films.

Still, I have to wonder who these people are that rate these films.

Significance

It can be argued that some swearing is overused and unnecessary but some films contain swearing because some people swear in real-life, and it can make a film more dramatic or shocking.

History

It depends on what is considered swearing, which has changed over the years as sensibilities change, and also on culture, but swearing dates back to silent films.

From The Douglas Fairbanks Museum:

Vintage news articles from the museum’s newspaper and magazine archives were requested by the network specifically pertaining to the 1916 Douglas Fairbanks comedy, The Habit of Happiness – reportedly the first Hollywood film to contain a curse word. And this was in the silent days before spoken dialogue!

Although there are no swear words in the printed title cards, Fairbanks reportedly swore up a blue streak in one particular scene, sparking a nationwide lip-reading movie controversy.

From IMDb's Gone With The Wind (1939) FAQ:

Was this the first movie to use profanity?

No. "Damn" was surprisingly common in intertitles of silent movies, and John Gilbert even shouts "Goddamn you!" to the enemy during battle in The Big Parade (1925), and cries, "Christ! He's dead!" in The Show (1927). Talkies that used "damn" include Glorifying the American Girl (1929), Gold Diggers of Broadway (1929), Hell's Angels (1930), The Big Trail (1930), The Dawn Patrol (1930), The Green Goddess (1930), Dirigible (1931), Blessed Event (1932), The 39 Steps (1935), The Man Without a Country (1937), and Holiday (1938). GWTW wasn't even the first Best Picture Oscar winner to use "damn": Clive Brook says it in Cavalcade (1933).

From Digital Spy Forums:

You'd have to define your 'swearing' boundaries.

I think Who's Afraid Of Virginia Woolf? (1966) was the first American film to feature a fairly liberal use of words accepted as 'swearing' (several bastards, bloodys and buggers), as opposed to just mild 'cussing' of the damn and blast variety. 'One or two' instances of those had been accepted in British films for quite a while though.

According to Wikipedia's fuck article (which goes into much more detail):

The films Ulysses and I'll Never Forget What's'isname (both 1967) are contenders for being the first film to use the word 'fuck,' although the word 'fucking' is clearly mouthed silently in the film Sink the Bismarck! (1960), and the title character says it in the cartoon Bosko's Picture Show (1933).

Since the 1970s, the use of the word "fuck" in R-rated movies has become so commonplace in mainstream American movies that it is rarely noticed by most audiences. Nonetheless, a few movies have made exceptional use of the word, to the point where such films as Fuck, Good Will Hunting, Casino, The Last Detail, Menace II Society, The Big Lebowski, The Departed, Scarface (1983), Pulp Fiction, Blue Velvet, South Park: Bigger, Longer & Uncut, and Goodfellas as well as the HBO TV series The Sopranos are known for its extensive use.

From several posters on the Straight Dope Message Board:

John Gilbert, via intertitle, shouted "goddamn it" and "b------s!" (sic) during the heat of the battle in the hugely successful The Big Parade (1925).

In the closing line of the exotic The Green Goddess (1930), George Arliss, as a Asian tyrant, dismisses a woman who escaped his clutches with the comment, "She probably would have been a damned nuisance, anyway."

Another World War I epic, Hell's Angels (1930), really let it rip: you could hear "It's me, goddamit", "What the hell", "For Chrissake", "Jesus!", and "That son-of-a-bitch!" amid the aerial dogfights.

Even after the Motion Picture Production Code began to be enforced in 1934, there were pre-Gone With the Wind uses of "damn", including Katharine Hepburn quoting Lady Macbeth's "Out, damned spot" in Holiday (1938). The earliest Code-era "goddamn it" I know of was from Don Murray in Bus Stop (1956).

Scott Wilson was the first to say "shit" in an American feature, as one of the murderers in In Cold Blood (1967).

The first major Hollywood film to use "bullshit" was Bullitt in 1968.

Coincidentally, I've been trying to find the first mainstream American movie to feature the most taboo word of all - "cunt". I know it was in Boys In The Band from 1970, but I think there may be an earlier instance.

Rip Torn in The Cincinnati Kid (1965): "Yes, for my kind of money, gut money. I wanta to see that smug old bastard gutted. Gutted!"

There are supposedly several cases from the silent era where lip-readers did complain about swearing in the dialogue. In this vein, there's a scene between Edmund Lowe and Victor McLaglen in What Price Glory (1926) that reputedly caused problems, as did some of Gloria Swanson's language in Sadie Thompson (1928). Similarly, there's the case of Douglas Fairbanks and the dirty joke in The Habit of Happiness (1916).

I'm led to believe that "I'll Never Forget What's'isname" (1967) was the first film to use the f-word.

As an interesting aside, here is a list of films in which the word appears most frequently.

From Wikipedia:

The films Ulysses and I'll Never Forget What's'isname (both 1967) are contenders for being the first film to use the word 'fuck,' although the word 'fucking' is clearly mouthed silently in the film Sink the Bismarck! (1960), and the title character says it in the cartoon Bosko's Picture Show (1933).

Some of Ken Loach's films have a huge amount of swearing in them. Sweet Sixteen must have the highest ratios of swear words to words overall.

His 1969 film Kes used the words "bastard" and "twat" a few times, and one case of "fucking". This seemed to pass without much controversy at all.

1933 Design for Living with Gary Cooper and the character of Gilda used the Fword when she is yelling at her husband and tired of hearing about Eaglebower.

The Wolf of Wallstreet was definitely the peak of profanity in cinema, though.

M.A.S.H. (1970) was the first major studio film to introduce the F word, which gave Hollywood the green flag. Generally speaking, profanity must have started from British cinema, rather than American, just like it did in literature.
