The first film to openly question the veracity of the Warren Commission's report into the death of John F. Kennedy.
Once the film was pulled from release in December 1973, it didn't show up again until the late 1980s when it finally started surfacing on TV.
Hugely controversial upon its release because of its depiction of the assassination of John F. Kennedy, the film was unceremoniously yanked from many theaters in its first and second weeks of showing because of the bad press. Many television stations also refused to run trailers for the film.
