Post-production
- This story was the first time the Doctor Who title sequence was created with a computer. Many of the effects, like the bubble Mel is trapped in, were realised in the same manner.
- Keff McCulloch arranged the new opening theme. It was used until the end of the regular run of the series. A new logo for the series was also introduced with this story along with a new opening credits sequence that moved away from the "starfield" motif introduced in 1980. The new theme arrangement marked the first time since the First Doctor's era that the theme's "middle eight" section was regularly heard during the opening credits (the previous two arrangements used the middle eight during the closing credits only). As with the opening sequence from the Sixth Doctor era, the Seventh Doctor's opening does not use a static image of the Doctor, but rather one with limited animation: the image starts as a scowl, then the Doctor winks and smiles. McCoy wears makeup that gives his face and hair a silver/grey appearance. Episode four mistakenly uses an early version of this sequence, which gives the Doctor's face a shadowy look which producer John Nathan-Turner felt was not prominent enough.
