Wikipedia's "List of films that most frequently use the [F-word]"
This Wikipedia article includes every movie that has over 100 instances of the F-word. At present, its chief source is Screen It! Entertainment Reviews ( http://www.screenit.com/all_titles.html ). The Family Media Guide was a former source that is now defunct, so the list is undergoing some revision to replace its information with Screen It’s.
What you see here corresponds with Wikipedia’s revision of 26 March 2009.
