The case of Duel has been discussed many times, and is an exception to the rule. This is because even though it was made for TV, it has had a wide theatrical release in several countries.
Pearl Jam Twenty is a really controversial one. I believe the information on IMBD to be very misleading. I mean, how can a documentary which had its premiere at The Toronto International Film Festival, and was screened in many cinemas around the world, (including my country, that is Poland) be considered a part of a TV-series? What I think happened was that it was simply broadcast on TV as an episode of a long running 'American Masters', hence the information on IMDB. But that hardly makes it an actual part of this TV series rather than a regular documentary. What's more, when I was uploading the shots, there was no sign of this information on the movie's page on IMDB, it must have changed recently. So, I would really like you to reconsider closing the movie for uploading :)
After some digging, it seems like IMDB maybe changed its catalogueing style and it had a theatrical release before it became a tv series, we are digging for more information. It is locked for now, but if it turns out that it is a good movie, we'll open it again and post here.
@Asmodai concering gay niggers: i usually don't check the movies main page before uploading so if you go through upload process you don't get this hint...
i don't know why, but it seems its one of some less exceptional. I know many more tricky exampels. One of that, Battlestar Galactica, the tv-series from 1978. At first an usual tv-series. In some countrys the pilot episode run in theatricals. Later they cut scenes of that series and made with them feature films. I know at least 3 feature films. For a long time there was just 1 shot in the archieve and the movie slot was locked. Later at a time of a tv-series contest, kinoute changed it finally to tv-series.
