Production Errors

  1. The Guard killed by The Master in part one begins to fall before The Master has used his laser. The Guard in question is seen alive and well in part two  

  2. The corpse of the Technician is clearly an action figure, and not the actor playing the Technician  

  3. After Hildred unlock one of the Tardis doors, the second guard to enter the ship bumps into the other door 

Working Titles

  • The Dangerous Assassin


The Deadly Assassin marks the first time where Gallifrey and Time Lord society become the focus of the story. For the most part the whole affair is basically a whodunnit and guess what? The mysterious killer is so obvious but then again all Doctor Who killers expose themselves at some point so what is new here? Impressive costumes, sets, lighting, and direction make the Time Lords to be a thriving race where class and order are the key to success. There is also a darker side to the Time Lords where they are willing to harm members of their own race for the greater good. Some of the best cliffhangers can be seen here opting for freeze-frames to up the tension which shows a lot of intelligence from Holmes on his behalf. There is a creative approach here; nonlinear storytelling, POV shots, flashbacks and brief voiceovers are used to keep the dangers The Doctor faces throughout. The Master meanwhile acts a sort of secondary villain who pulls all the strings to get what he wants through others and only leaps into action when others have failed him. Episode two and three contain some of the finest and most creative moments mainly the various disguises used by the Killer. The Deadly Assassin is beloved by many Doctor Who fans of all ages, with its satirically political humour and dark gothic qualities firmly places it as a highlight in Renaissance era. *****​
