Production Errors

  1. Towards the end of The Poison Sky, the Sontaran's weapon are targeted on the Earth. However when the Sontaran ship is destroyed all weapons are closed 

  2. During the warehouse battle, when The Doctor says 'Hold on, I'm Coming', the film crew can be seen reflected in a door towards the right of the screen 

  3. When Colonel Mace confronts Commander Skorr, he raises his gun twice in the same scene 

  4. When Luke Rattigan teleports onto the Sontaran ship, he catches the detonation twice, in the same scene

Working Titles

  • [no known working titles]


A strong two-part story which excel in setting up the main themes and issues of the story but falls short on a few areas to become an instant classic. The Sontarans are brought back in style with a new looks and costumes whilst staying true to their roots. This marks the first time where UNIT are properly used, investigating suspected alien activity with a new wannabe knockoff Brigadier who is not that strong as a leader. The cliched child genius makes another appearance, thank goodness Luke does not have a twin, who is used properly to the story’s narrative and never gets in the way or become inevitably annoying. The pollution and emissions storyline unlike Gridlock brings a devastating reality for everyday life on Earth and the Sontarans are used in a smooth manner. Whilst The Poison Sky is a little underwhelming than The Sontaran Stratagem the script is tightly written with plenty of time for a few side lines and characters. A great two parter which uses one of the most memorable monsters from the classic series invigorated in new ways which are perfect for the twenty-first century. Robert Holmes would be proud. ****​
