Production
This episode had the working title "World War II". Early versions of this script quoted this episode's title as being "An Empty Child". This is a reference to "An Unearthly Child", the very first episode of Doctor Who. The episode's television listings information and the DVD cover also mention that "London is being terrorised by an unearthly child".
Location filming took place at the Barry Tourist Railway. Barry Island and its now-demolished Butlins holiday camp had previously been the filming location of the Seventh Doctor serial, Delta and the Bannermen. The sound of Dr Constantine's skull cracking as his face changes into a gas mask was considered too horrific in its full form by the production team and was cut before broadcast. However, writer Steven Moffat claims on the DVD commentary to this episode that the sound was discussed but never put on. According to the Doctor Who Confidential episode "Fear Factor", the effect was added in the version of the episode presented on The Complete First Series box set.
Unlike previous episodes, the "next episode" trailers were shown after the end credits instead of immediately preceding them, possibly in reaction to comments after "Aliens of London" about having the cliffhanger for that episode spoiled. This trend has continued for most two-part stories in the new series. Captain Jack's line explaining the nanogenes was not audible in either the original or repeat broadcasts on CBC Television in Canada. It was also removed from the UKTV Gold and US Sci Fi Channel broadcasts, although the lines were still present in the subtitles. This adds some confusion to Rose's next line, "Well, tell them thanks!" The cause for this change is unknown.

Famous quotes containing the word production:
“In the production of the necessaries of life Nature is ready enough to assist man.”
—Henry David Thoreau (1817–1862)
“The growing of food and the growing of children are both vital to the family’s survival.... Who would dare make the judgment that holding your youngest baby on your lap is less important than weeding a few more yards in the maize field? Yet this is the judgment our society makes constantly. Production of autos, canned soup, advertising copy is important. Housework—cleaning, feeding, and caring—is unimportant.”
—Debbie Taylor (20th century)
“The development of civilization and industry in general has always shown itself so active in the destruction of forests that everything that has been done for their conservation and production is completely insignificant in comparison.”
—Karl Marx (1818–1883)
