Doctor Who: 5 NuWho Episodes That Were Actually Sequels Or Prequels To Classic Stories
1. The Curse Of The Black Spot
In the third episode of Series 6, The Eleventh Doctor, Amy, and Rory found themselves trapped aboard the ship of real life Pirate Captain Henry Avery. During the course of the episode, Avery's treasure hoard is dumped overboard in the hope of saving the ship and crew from a supposed Siren's curse.
As it turns out, 'The Curse Of The Black Spot' serves as a prequel to a lost First Doctor story, 'The Smugglers'. Taking place after the death of Henry Avery, the story sees The Doctor fending off a gang of smugglers on the hunt for Avery's lost treasure.
Interestingly, 'The Curse Of The Black Spot' was an accidental prequel. Steven Moffat simply wanted to use a real pirate for the story. The fact that the events of 'The Curse Of The Black Spot' fit perfectly with 'The Smugglers' was a lucky coincidence.
