Although Marvel Studios released the first footage from Captain Marvel only today, production is well under way on merchandising tied to its March 2019 release. For proof, you need look no further than the Twitter account of star Brie Larson, who posted a photo of an action figure, accompanied by an important question.

Based on Larson's likeness from the film, the figure is clad in Carol Danvers' blue-and-red uniform, and lists accessories: an additional head and two additional hands. It's the former that caught Larson's attention, leading her to ask, "What's the additional head?"

It's likely the additional head is the helmet Captain Marvel has worn in the comics, and is glimpsed in the teaser trailer.
