Memory worms are used again to delete memories, this time of the Doctor and his heist team.
This is the second episode, after Robot of Sherwood to capitalise its title during the opening credits.
Also it shares the same pre-opening theme sound with Robot of Sherwood which, interestingly, is the Seasons 1 to 4’s.
The script and rough-cut of this episode were leaked online before it was broadcast.
Keeley Hawes (Ms Delphox) is not credited as Karabraxos, presumably as she appeared mostly as Delphox.
The episode contains an image of Abslom Daak, a character who originated in comic stories. This is one of the few examples of a episode referencing a character who originated outside of the series itself. Daak’s image appears among a number of other characters from past seasons of Doctor Who and The Sarah Jane Adventures. An image of James Marsters as Captain John Hart is also seen, marking the first on-screen reference to a Torchwood character in Doctor Who since The End of Time Part 2.
The Teller is played by Ross Mullan. You may not recognise his face but he also played a Silent in The Time of the Doctor
“Or we could go to Brighton…” If The Doctor suggests a trip to Brighton – watch out! When he tried to take Leela to the coastal resort they ended up miles away, on Fang Rock, facing a Rutan invasion. Later, when he attempted to attend the opening of the Brighton Pavilion he got the time wrong and the place right but the visit still ended in disaster when K9 was blown up whilst taking a dip on Brighton beach! Check out Horror of Fang Rock and The Leisure Hive to find out more about both adventures.
“You agreed to rob the most impregnable bank in history…” Looks like The Doctor has got over his antipathy towards that adjective! In Robot, the Fourth Doctor tells the Brigadier that he, ‘Never cared much for the word impregnable. Sounds a bit too much like unsinkable.’ When his old friend asked what was wrong with ‘unsinkable’, he replied, ‘Nothing, as the iceberg said to the Titanic…’
