Há uma longa página na Wikipédia da Tardis que detalha muitas das mudanças e mostra como às vezes é apenas uma caso dos fabricantes descobrindo algo de que gostam:
Deep Breath saw the debut of a new title sequence originally designed by Billy Hanshaw, after executive producer Steven Moffat discovered a popular video of the graphic artist's conceptual Doctor Who title sequence on YouTube. Moffat, delighted with how new and innovative Hanshaw's ideas were, got in touch with him to create a professional version of his sequence for the actual series.
Tenha em atenção que esta sequência de títulos foi frequentemente alterada ligeiramente:
Starting with The Magician's Apprentice, the clock gears, the gas and the first clock face tunnel have a purple hue.
This sequence received many one-off modifications during its usage. In Death in Heaven, the Doctor's appearance was replaced with that of Clara Oswald (Jenna Coleman) and her credit placed before his to reflect her ruse to the Cybermen that she was the Doctor. In Heaven Sent, Capaldi's name is held on the screen longer - as he is the only actor credited in the title sequence.
When this title sequence was used in Christmas episodes, a wintry feel was given to the title sequence. In Last Christmas, the first unwinding clock is icy/frosty and the TARDIS is covered in snow. Snowflakes appear in the second Time Vortex and the special guest credit for Nick Frost as Santa Claus is delayed until the sequence is nearly complete.
E um episódio teve uma sequência de títulos completamente diferente:
The title sequence introduced in Deep Breath was temporarily ditched for a silent title card, which was used to to fit with the "found footage" theme of the episode. This title card features the names of the characters and locations from Sleep No More alongside randomly picked numbers. The words 'Doctor Who' can be seen spelled vertically through the names of other characters. The title of the episode is not seen in this title card, and instead appears during the closing credits, including the writer, Mark Gatiss and director, Justin Molotnikov.
