Production Errors

  1. Whilst being chased by ghosts and heading towards the Faraday cage, Jenna Coleman ducks below the camera 

  2. If The Doctor nor Clara have told O'Donnell about the Tardis, how does she know its on the other side of the flood doors? Perhaps she saw it on a security camea

  3. Towards the end of Under the Lake, a boom microphone shadow can be seen across Clara's face

  4. Whilst The Doctor explains the ghosts to the crew, his body position and the lighting change 

  5. The Fisher King's gun is strangely missing when he watches the dam break up. The gun is back in his hand when he roars as the flood approaches him 

  6. When Prentis discovers the bandages inside the spaceship, they strangely rearrange themselves between shots

Working Titles

  • Ghost in the Machine


A excellently put together base under danger episode compared to other similar stories 130 etc. The cinematography and sets are superb with a lot of detail suggesting a sense of isolation and dampness. The plot is beyond excellent incorporating time-travel, different timelines, alternative timelines, and paradoxes. Very easy to follow and very engaging all thanks to the first fifteen minutes which set up the nature of the episodes and beyond. Some of Whithouse’s finest moments after a brief absence working on the show. One of the all-time best cliffhangers and Capaldi showing off his talents as a ghost are only just but a few highlights to the episodes. Visual effects such as the water flooding the base and the Fisher King, an all-around awesome villain, even if he doesn’t appear for a long time. Excellent. *****​
