20 Most Controversial Movies Of All Time
6. Deep Throat
Deep Throat, one of the first high-end pornographic pictures to receive mainstream attention, told the story of....well, the title has that covered. Deep Throat was banned in various locations in the United States on the grounds of obscenity, but this attempt at censorship backfired, and the film went on to become possibly the most popular adult film of all time.
Deep Throat isn't notable for being particular graphic in its depictions of sex, but rather for becoming such about as large of a piece of American culture as an adult film ever could be. It's most notable influence is undoubtably the fact that the informant who helped break the Watergate case that brought down President Nixon chose Deep Throat as his pseudonym.
