Trivia

Chris Chibnall described this episode as "a lovely big Earth invasion story" but different from the ones done before, as it focused on Amy and Rory's time with the Doctor and the impact of him on their lives. See more »

Goofs

The cubes are meant to be completely identical and with 'no flaws' to their perfect cubic nature whatever. Just after the soldier's enter, the doctor picks up a cube and plays about with it, tossing it and turning it over in his hands. At the last moment of the shot, a dent and a line, possibly from tape meant to keep the cube together, can clearly be seen at the top of one of the cubes. See more »

Quotes

Brian Williams: [on Amy and Rory] How long were they away?
The Doctor: I don't know what you're talking about, Brian.
Brian Williams: Because they're wearing totally different clothes from earlier.
The Doctor: Seven weeks. I got sidetracked. A lot.
Brian Williams: What happened to the other people who travel with you?
The Doctor: Some left me. Some got left behind. And some, not many but... some died. Not them. Not them, Brian. Never them.

Great Episode
14 October 2018 | by xxswagzbeastzxxSee all my reviews

An interesting episode, interesting to show an episode spanning over a long time, however it does feel a bit slow at times due to this.
