- Hilarious in Hindsight: The Doctor proudly proclaiming "I am the Master!" would become this in five years time.
- Retroactive Recognition: Boba Fett is one of the Xerons.
- Signature Scene: The Doctor hiding inside a Dalek casing. The moment when his head pops out, grinning, is one of the iconic images of the Hartnell era, guaranteed to be included in any montage of his tenure.
- Visual Effects of Awesome: The effects in the first episode are amazing for the time and would have been incredibly difficult to do. Vicki's reverse-playback dropped glass is the obvious one, but the way the TARDIS crew seamlessly walks through objects still looks good today.
