Background information 
With Christine Chapel having become a very popular character, fans were extremely excited about possibly seeing her in the alternate reality introduced in the movie . Recalled co-writer Roberto Orci, "Even before the first movie came out, a lot of online chatter was, 'Is Nurse Chapel gonna be there?!" 

In an interview with screenwriters Alex Kurtzman and Roberto Orci, Kurtzman explained, "In our original, original draft we wrote some scenes with Nurse Chapel but ended up losing them. Even in our first draft it's not included. We originally had a flirtation between her and : Nurse Chapel was obviously really obsessed with him and he was not giving her the time of day, which we thought was funny, but then we came onto the Spock/ connection [established in the film] and that's why Nurse Chapel ended up by the wayside." ()

Although not seen directly on-screen in the film (the  says she was not seen on-screen), Chapel's presence on the Enterprise is established in dialogue. McCoy calls for "Nurse Chapel", just after Kirk's hands swell up from the vaccine. Near the end of the film, as Kirk, Spock, and Pike beam back from the Narada, a blond-haired female medic with a 1960s-style beehive hairdo is seen administering to Pike; this could actually be Nurse Chapel.

In the lead-up to the release of , some fans guessed that Alice Eve might be portraying Nurse Chapel.  This was later disproved, though, with Eve instead playing . The screenwriters opted to nevertheless reference Chapel in the film. "We just figured that would be a great reference," noted Alex Kurtzman. The way it helped establish Kirk's attitudes to women, such as that he forgot Chapel, was the reason the in-joke was used. 

When asked if Chapel could actually appear on the Enterprise after being referred to in Star Trek Into Darkness, Roberto Orci laughed and stated, "That's certainly possible!" 

In a deleted scene from ,  actor Karl Urban ad libbed a line in which he, as McCoy, said that Nurse Chapel had contracted the gangorian clap from Kirk, and that she wasn't happy about it. ("Gag Reel",  Blu-ray special features)

Apocrypha 

During an away mission in "Operation: Annihilate, Part 1", the fifth issue of the Star Trek: Ongoing comics series, Kirk requested that a security officer in the landing party beam back to the Enterprise and inform Nurse Chapel of the landing party bringing more casualties from Deneva up to sickbay.

In "Parallel Lives, Part 1", a male version of Chapel had not transferred from the Enterprise, unlike Christine.
