Doctor Who Exclusive: The Smugglers Missing Episode Has Been Found?
It features pirates and takes place in Cornwall. And it's been lost for years.

Lastly, and most importantly, there's the so-called "omnirumour". This particular rumour states that way, way more than 11 missing episodes were recovered in Nigeria/other parts of Africa. And when I say "way more" what I actually mean is "96 of 97 missing episodes have been recovered". The lone exception seems to be "The Feast of Stephen", which was a Christmas special that happened during "The Dalek Master Plan" and was apparently never sold abroad. This rumour has been circulating for a while, and has gained much traction through the actions of professional fan/occasional hero/sometimes supervillain Ian Levine. He's one of the people responsible for saving some of the many episodes that we do have, and for that fans everywhere should buy him a drink. He's also occasionally been known to be a bit prickly and hard to deal with. He come into this because he's been saying, on his Twitter feed, that 96 out of 97 episodes were recovered and are being held back for reasons undetermined. He constantly says he has "evidence" of all these things. Now I take no stand on whether or not he's telling the truth. I can't think of any reason that he'd be lying, but I also can't think of any reason that the BBC, or anyone else, would be holding back another 96 missing episodes. Surely if we got to the point where there was one (1) episode missing, that would be a cause for great joy, and the BBC would be able to sit back and print money by selling them. So for them to hold out makes no sense. So...as for the omnirumour, I'm unable to take a stand. Either Levine is telling the truth, and the BBC are hiding the fact that they have many more episodes for some odd reason, or the BBC genuinely doesn't have them, and Levine is, for some reason, saying they do. While I certainly hope that 96 episodes, or even 1, or 20, or whatever, have been recovered, I don't have any opinion at all on the omnirumour.
The last rumour is that we'll all hear what's been going on somewhere around Easter. Of all these, this is the only one I really honestly believe. I believe that sometime around Easter, the BBC will announce...something. My guess is that they will say another set of episodes have been recovered, restored, and are ready for purchase. Probably this will be "Marco Polo" and something else. Of course, we've all been burned before, and this could all amount to a great big pile of nothing. It could be smoke and mirrors, and every episode that is missing could be genuinely gone. I hope that isn't the case. I hope at least some of these rumors are true. But I guess we'll all find out soon. As the Doctor once said, "Time will tell. It always does."
