- Ensemble Dark Horse: Bill Filer and Pigbin Josh have received their own little fan-gatherings.
- Fight Scene Failure: The Axon chucking itself at the jeep.
- One-Scene Wonder: The UNIT soldier who appears to be having a lot of fun running down Axons with his truck.
- Special Effect Failure:
- The story starts off with a spaceship approaching a Matte Shot of the Earth in space... a black-and-white photo. Admittedly, the vast majority of British people in 1971 were still watching on black-and-white sets, but still...
- The frog clearly does not look like its sitting on the rock properly.
- In episode two, during the "absorption" scene, the Axon Woman's mask fails to inflate properly due to the stuntwoman not fitting the size of the mask making it appear to deflate and the mouth was where the mask's nose was when the stunt double is breathing in. This is even commented on in the production notes. Given the trippy nature of the story, this could be a subverted example as the resulting effect is actually quite Uncanny Valley and pants-shittingly effective as a result.◊
- Unfortunate Character Design: The phallic eye of Axos.
- Visual Effects of Awesome: The scene where Jo Grant is nearly aged to death is quite well-done with the blending of actresses.
- The pyschedelic effects that place on Axos are quite colourful and spectacular, especially the brain scanner in Episode 1 and 2.
- The effect of the Axon Man turning his head as he addresses the Doctor and Jo in Episode 3.
