Over the course of the last fifty-one years, there have been many, many proposals for Doctor Who episodes that justnever made it. Wikipedia has a whole article devoted to this concept. Some of these stories never made it past the cocktail napkin stage, but others were actually bought, paid for, and ready to shoot before various things (usually cancelation), stopped them from being made. In some cases, this was a very bad thing. In other cases, such as the ideas for the American 8th Doctor TV series, this was nothing but a very, very good thing. Seriously, go read about The Leaky Bible, and just try to deny the point. This is just a short list of whats out there as far as unmade episodes, and its devoted only to Doctor Who episodes. There were several planned for The Sarah Jane Adventures, as well as ideas for various anniversary episodes, an animated series, and a couple different movies, but well ignore those for now. It is true that all the various ideas vary in quality, but they all have this in common: they will never grace our TV screens. Whether that is good or bad is up to you to judge, but here are the ones we think had the most potential.
