Trivia
The script was originally structured so that the scene in which K-9 departs with the Doctor and Leela could simply be dropped if the character was not to be retained, leaving the implication that he had simply been returned to Professor Marius off-screen.

Quotes
Doctor Who: [taking a blood sample] You're not frightened of blood, are you, you mighty huntress?
Leela: [unphased] Just hurry up.

Pretty good.

Ignoring the cheap sets, this is one of the better episodes of Doctor Who. Its clever and original. The story is weird but fun. The actors are all great. I'd recommend this episode - especially if you're a fan of the show.
