Crew

The Doctor

 * The Doctor speaks both Dinosaur and Horse.
 * The Doctor enhances the TARDIS control room with furnishings such as a chalkboard, bookshelves, and a recliner. He also changes the cold blue neon piping in the time rotor to a warmer amber, adding an ambient feel to the console room.

Specific to theatrical presentation

 * A specially recorded scene similar to the Strax Field Reports was shown before the episode in its showing in cinemas featuring the Paternoster Gang: Vastra, Jenny Flint, and Strax. The scene primarily focused on Strax humourously describing the first twelve incarnations of the Doctor, making note of the War Doctor as well as the Tenth Doctor's aborted regeneration, to his people, before alerting them to the appearance of the latest Doctor.
 * A behind the scenes feature similar to the previous Doctor Who Confidential, entitled Doctor Who Extra, focusing on both the production of this episode and Peter Capaldi's inauguration as the Twelfth Doctor, was screened to participating cinemas following the showing of Deep Breath. This was in turn followed by a live Q & A in London, hosted by Zoe Ball with Peter Capaldi, Jenna Coleman, and Steven Moffat, was screened to cinemas following the showing of Deep Breath.

Common among all versions

 * This episode saw the debut of a new title sequence designed by Billy Hanshaw after executive producer Steven Moffat saw a video of his conceptual Doctor Who titles sequence on YouTube and decided to draft him aboard to do a professional version of his sequence. The new titles features a vast expanse of golden-bronze clock gears whizzing by in empty space, and then the TARDIS flying through a tunnel of Roman numeral clock face numbers spiraling into a literal depiction of a time vortex with glowing engravings of circular Gallifreyan. The TARDIS passes across the screen in a way very similar to the Series 1 title sequence as the TARDIS jumped from the blue to red time vortex, and then launches past a group of planets. Peter Capaldi's piercing eyes are shown, rather than a full insert of the actor's face.

Continuity

 * The Twelfth Doctor often reflects that he finds the current situation of robots harvesting human organs to repair a ship to be naggingly familiar (TV: The Girl in the Fireplace), but his addled brain is unable to make the connection even when he notes that the ship- the SS Marie Antoinette- is the sister ship to the SS Madame De Pompadour.
 * The Doctor mentions Amy, making reference to her legs. (TV: The Impossible Astronaut)
 * While performing a physical examination of Clara, Strax makes an observation on her thorax as did Linx with Sarah Jane Smith (TV: The Time Warrior) as well as Commander Skorr to Martha Jones. (TV: The Sontaran Stratagem)
 * The Doctor wonders who gave Clara the phone number of the TARDIS. (TV: The Bells of Saint John)
 * The Doctor is sure he has already seen his new face before, and comments are made that suggest someone else used it before him, creating frown lines. (TV: The Fires of Pompeii)
 * The Paternoster Gang are located in the Victorian era. (TV: The Snowmen, The Crimson Horror)
 * Clara learns why the TARDIS telephone was hanging off the hook when she returned to the TARDIS after the Eleventh Doctor began regenerating. Because he did not patch it back to the console unit, the Eleventh Doctor dragged the phone by its cord into the entrance of his console to make a private and final phone call to Clara in the near future, then neglected to properly hang up the phone with his time running too short to worry about it. (TV: The Time of the Doctor)
 * The Doctor can speak horse. (TV: A Town Called Mercy)
 * The Doctor and Clara yell "Geronimo!" as a code word to spring the Paternoster Gang into action, a catchphrase used by the Doctor's previous incarnation. (TV: The End of Time et al.)
 * Jenny snaps at Vastra for calling humans derogatory terms because they're married. (TV: A Good Man Goes to War)
 * Strax mentions using deadly acid again. (TV: The Crimson Horror)
 * When Clara sees the improved console room, she says, "You've redecorated... I don't like it." This was said verbatim by both the Second and Tenth Doctors at the sight of new TARDIS console designs. (TV: The Three Doctors, The Day of the Doctor)
 * The Doctor wishes he had more "round things" in his updated control room. (TV: The Day of the Doctor) He remembers he "had many round things once" and wonders where he put them.
 * Clara's first and last interactions with the Eleventh Doctor are over the phone. (TV: The Bells of Saint John)
 * The Doctor states that he is over 2,000 years old.
