When was the last time you saw a movie that didn't have a curse word in it? Unless you only watch kids' movies, chances are it's probably been a while.

In the video above, we get a history of the profanity found in Hollywood films. The first curse word was used in 1929, just two years into the invention of film with sound.

While the video credits Al Pacino for the saying "fuck" the most times on film, the film that uses the f-bomb the most is actually Martin Scorsese's 2013 flick, "Wolf of Wall Street," which used the f-word a whopping 506 times.

Swearing in films is no longer as shocking as it once was in North America, but in more conservative countries like the United Arab Emirates, films depicting excessive drug use and religious profanity are often encouraged to make additional edits, reports The National.

Hollywood films that do use excessive swearing are typically rated R, so to avoid restriction, many writers, directors and editors get creative with language use and scene cuts.
