Synopsis

 * While the Doctor says in this episode she's never had a flat before, previous stories such as PROSE: Verdigris and PROSE: Endgame indicate otherwise.
 * The plot of the episode is similar to the films Ice Spiders and Eight Legged Freaks due to using both the themes of scientific blunders from the former and toxic waste mutating normal sized spiders from the latter.
 * The title of this episode is a play on the Sex Pistols song title Anarchy in the UK.
 * Almost every science fiction fact about spiders mentioned or done in the episode has its ground in real-world science.
