- Memetic Mutation: "The one with the fwhite hair."
- Special Effects Failure: The Sensorites have visible zips down their backs.
- Visual Effects of Awesome: There's the major technical triumph of showing the TARDIS crew going through the TARDIS control room, leaving the doors and stepping out onto the spaceship they've landed on in one continuous, seamless movement. There is a cut to facilitate this, but it's very subtle and the mind refuses to register it. Nowadays, an effect like this would be trivial, but the series spent decades trying deliberately not to show this movement under the grounds that it would be unconvincing, despite it being executed seamlessly almost right at the very beginning.
YMMV / Doctor Who S1 E7 "The Sensorites"
