Production Errors

  1. The drivers' seat in the episode is on the right side of the car. This is despite the fact that the driver seat in New York vehicles are always on the left side of the car 

  2. When The Doctor opens the bottom door of the Businessman's car, the computer voice fails to say 'capsule open' compared to all of the others time when The Doctor open the bottom door 


Working Titles

There has never been a Doctor Who serial which crams so much into the story and successfully pull off a perfectly told forty-five-minute tale. The script explores so many themes, faith, drug use, depression, pollution, society, desperation, denial; the list could go on. Beautiful writing is met with some of the most shocking moments – the rundown pharmacy town, the thousands of cars on the motorway all with their polluting fumes and gas, the reveal of the upper city and the true reason why no one is trying to help the trapped souls on the motorway. Gridlock showcases that it is possible to tell a story which is supposed to stir up a whole array of emotions and where not everything will always be fine whilst travelling with The Doctor. Once again the cast is brilliant, easily one of all-time best and that’s saying something since the show has had a series of great ensembles in the past. The Doctor begins to open up to Martha and the final shot of the episode truly captures the beginning of something new and wonderous. An instant classic. *****​
