I've seen 6, 8, 13, 17, 18. I too am surprised that Faces of Death was not on here as its claim to fame is being the most banned films of all time. Birth of a Nation and Within our Gates have some text in them that you couldn't get away with saying now on tv. Kinda of surprising. I remember having to watch them in college to write a paper and I couldn't believe what they got away with. The life of Brian, Scarface and The Last Temptation of Christ are all good movies.
Watch some reruns of All in the Family, Good Times, or Sanford and son. They say stuff on there you can't say on t.v. now and probably wouldn't get away with on this forum.
