Production Errors

  1. Zoe apparently doesn't know how candles work yet in The Mind Robber she recognises candles without haste

  2. At the cliffhanger of episode three, The Doctor and the others' screams are heard for ages, but at the start of the next episode they've only fallen a few feet

  3. There are numerous noisy explosions in space when sound can not travel in space

  4. Numerous model shots of space appear to be missing stars
