From Variety by way of Matt Drudge, a Hollywood guy who ought to know better:
‘Wolf of Wall Street’ Breaks F-Word Record
Martin Scorsese’s “The Wolf of Wall Street” is all about excess. From orgies on a plane to cocaine and cash (or “fun coupons” as Leonardo DiCaprio’s character calls them), the financial drama thrives in taking it up a notch.
So it should be no surprise that Paramount’s R-rated film sets the all-time record for the use of the f-word.
According to Wikipedia, the word “fuck” is used 506 times over “The Wolf of Wall Street’s” 180-minute running time. Previously, the record for a non-documentary was Spike Lee’s 1999 film “Summer of Sam” with 435 instances.
The script was completed in 1970, but contained too much profanity to be shot as written. Columbia Pictures waited for two years trying to get writer Robert Towne to tone down the language. Instead, by 1972, the standards for foul language relaxed so much that all the profanity was left in.
How vulgar was it? This must be hyperbole, but still...
Ayres convinced Columbia Pictures to produce the film based on his consultant's credit on Bonnie & Clyde but had difficulty getting it made because of the studio's concern about the bad language in Townes's script. Peter Guber recalls, "The first seven minutes, there were 342 'fucks'"
That is roughly fifty per minute, or one per 'effin second. However, the Wiki-crowd may have been deceived by pale substitutes:
A tamer version with less profanity was filmed at the same time for TV showings. Because of the amount of swearing, the entire movie was pretty much shot twice.
