Rounding out the Doctor Strange cast is Rachel McAdams as Christine Palmer. The character originally appeared in Night Nurse, a 1970s Marvel series following the adventures of three young nurses working at a New York hospital. The series didn't last long, but it became something of a cult classic, and the character Linda Carter made a number of appearances as in other comic books, adopting the "Night Nurse" name for her work treating injured superheroes. However, Christine Palmer largely faded into obscurity (except for a brief fling with Nightcrawler in the early 2000s) until Marvel decided to resurrect her for the movie.
They made a number of changes to the character, who is now a surgeon and an old friend/flame of Strange's. Marvel boss Kevin Feige told Slashfilm that the studio went with Palmer over one of Strange's supernatural love interests from the comics because "we wanted a grounded character … somebody that could be his anchor to the real world." She also won't be adopting the "Night Nurse" persona used by Linda Carter, although Feige did hint that the studio might consider it for the sequels. All of which makes it somewhat puzzling that the studio chose Palmer over Carter, who actually did date Strange in the comics.
