Production Errors

  1. The first model shot of the Bi-Al Foundation already has the damage caused by the shuttle crash later-on 

  2. An entire wall shakes when Lowe presses the distress button in his office

  3. The knife that Leela uses to kill Meeker wobbles back and forth after Meeker falls to the floor  

  4. Somebody can be seen moving at the back of the set at the beginning of episode two 

  5. A camera and crewmembers can be been reflected in Marinu's nurse head-mirror at one point 

  6. The shadow of a boom mic can be seen when The Doctor congratulates himself for blowing the Swarm up

  7. The clones of The Doctor and Leela should have been naked when created, and not wearing clothes 

  8. Professor Marius seems very content letting K-9 go, considering he sees the robot dog as his best friend 

  9. Several guns appear to have no triggers or holes in the barrel 

Working Titles

  • The Invisible Invader

Verdict

The Invisible Enemy is one of those serials which look good on paper but not necessarily on-screen. The Invisible Enemy is another example which proves that the Baker-Martin duo continually provide storylines which just cannot be made on the restricted Doctor Who budget. A slow-moving first episode is followed by three more equally slow and tiresome episodes. There are good visuals but the main focus of the serial – travelling through The Doctor’s brain is seriously underwhelming. CSO takes dominance over constructed sets and whenever the two are mixed together the end result is rather disappointing. The Nucleus (one of the worst Monster ever in the show’s history) is very weak, taking over everyone it comes into contact. The Nucleus possess no credible threat considering the humans its possess have to help it move around the place. There was certainly a lot of potential here to create a dynamic story which explores the inner working of The Doctor's brain. Considering the story only gives ten minutes of The Doctor and Leela wondering inside The Doctor's brain there is very little reason to get excited about. Not bad. Just a big mess. **
