Production Errors

  1. There are numerous problems with CSO shots with dinosaur models and the backgrounds. Some of the dinosaurs appear to float on screen 

  2. The plot point about Sarah Jane being on a spaceship for three months is spoiled when the narrative cuts back to Earth, making it clear that she has not been on the ship for months but rather a few hours at most 

  3. When the pterodactyl flies into the garage, the wires operating the puppet are visible

  4. The Tyrannosaur Rex has far too many fingers on each hand and the wires which control the jaw reflect light

  5. The Tyrannosaur Rex doesn't roar, but rather it says "roar!"

  6. During episode six, The Doctor is driving a Land Rover, and the Brigadier is clearly in the passenger seat. Then all of sudden the Brigadier is the one driving, and The Doctor is in the passenger seat 

  7. The cut on Sarah's forehead appears on the wrong side of her head 

  8. Martin Jarvis seems to bash his head when getting into the lift during the tub station scenes

  9. The metal shutters which make up a part of the underground sets, cause the walls to shake when they descend ​​​

Working Titles

  • Bridgehead from Space - (storyline)

  • Timescoop


Invasion of the Dinosaurs again shows that science fiction does not need to be all fancy with aliens’ fleets and armies and spaceships who plan to take over the Earth. Another great script from Hulke is full of great ideas and intelligent writing but is hampered down by the puppet Dinosaurs. Some lossy CSO work and rendering issues make for an uncomfortable watch but at least the production team were trying something new and that’s what counts. There are other admirable production values and complex layers of the plot which keep things going despite some obvious plot holes and recycled ideas from previous episodes. There are numerous moments of surprise from Yate’s betrayal of UNIT to the hidden truth behind the Dinosaurs and the reveal of various surprises enemies. Pertwee gives a solid performance which reminds viewers that his wit and charm will surely be missed very soon. There are some repetitious material towards the end of the serial and the fate of the villains is rather chaotic. A great six-parter which misses out on so much. ****​
