On Video?

The most common theory is that it was taken out of release so quickly because of the upcoming release of the Movie. Hand Of Fear was the last release before the Movie aired and the more widespread theory is that the BBC expected that the popularity of the Movie would go through the roof and a new series would be picked up straight away, so rather than having people love the movie and then check out old videos with lower production quality, an attempt was made to recall as many of the videos as possible ready for a new wave of merchandise off the back of the moview and new series.

Obviously a series was never commissioned and the popularity of the Movie wasn't what they were expecting so it sort of backfired. That could all be a load of tosh, but its the rumour I have heard the most regarding it.

As for the videos that were bought, I have heard rumours of them selling at really high prices, but I always assumed it was a bit of a myth built out of the fact that it was only available for two weeks. On Ebay and Amazon now they go for standard prices generally, but the DVD is widely available now so that could be why.
