It’d be impossible to miss Stan Lee’s cameo in Captain Marvel, but did you happen to catch the other important comics creator to appear on screen? The scene itself is relatively easy to miss, especially if you’re not on the lookout. As Carol’s moving out of the subway station, she makes eye contact with a red haired woman and they nod approvingly at one another — no fun gags or jokes, just a tiny nod and they’re both on their way — but the nod is more enough, because that woman just so happened to be Kelly Sue DeConnick, the comic writer who spearheaded the reinvention of Carol Danvers into the hero we know her as today.
Strange as it may sound, Carol actually hasn’t been using the Captain Marvel codename for that long, despite existing in the comics for over 50 years. She got her start as Ms. Marvel back in 1968, and, with only a couple temporary name changes to monikers like “Warbird” and “Binary,” Ms. Marvel is what she stuck with until 2012. It wasn’t that she and the original Captain Marvel were unrelated to one another — Mar-Vell was a major part of Carol’s origin story — but she just never seemed to be in the right place to actually step into her former mentor’s mantle. At least, until DeConnick and her creative collaborators came along.
