Story notes

 * Transmission of this episode will be delayed one week by the Eurovision Song Contest, as was the case last year with a gap between The Lazarus Experiment and 42.
 * According to Russel T. Davies this episode is more frightening than Steven Moffat's terrifying series 3 episode Blink, which rated a 5.5 out of 5 on the the offical Doctor Who website 'Fear Factor' feature.
 * Proffessor River's Sonic Screwdriver fires a ray similar to the one produced by Captain Jack Harkness's sonic blaster. (DW: The Doctor Dances). This may be a deliberate reference that will be explained in The Forest of the Dead.
 * While the Doctor is hacking into Eve's tv she is watching the CBBC show Pedro and Frankesheep which makes it the second time this series someone has been watching a real-life kids show after The Doctor watching Tommy Zoom in The Poison Sky and the third since the series revival.

Cast Notes

 * Steve Pemberton is the second of the League of Gentlemen to appear in Doctor Who, the other being Mark Gatiss who appeared in The Lazarus Experiment as Richard Lazarus.
