  1. There are mistakes on the map in the 100th Floor Lobby of the Harmony Shoal Office. The map is supposed to show the capitals of every country. There are quite a few errors where the capital city is incorrectly marked ​​

Working Titles

  • [no known working titles]


The whole episode is fun and adventurous and takes a dive into something which the show has never done before – Superheroes. Some cool ideas match the aesthetic feel of the episode and are edited well enough to make it look expensive and thrilling but the plot is not really seen until halfway through. The episode fails to mention what the aliens actually want and what they do ‘want’ is a little underplayed. The classic love story is thrown in and foreshadows the more important stuff and is so cliched it feel like everything crumbles around it. Nardole is nowhere to be seen for long periods of time and moments seem to mirror other stories. The whole thing is fine for a Christmas special and is a festive treat for any time of the year. ***



Number of Production Days: 5
