Looking at this cover the first thing you see is Beyoncé posing in minimal clothing and holding a gun while holding an attractive gaze. The way she posing and is dressed compared to the men in the photo is a way to make her more the center of attention and for buyers to be more interested in watching the movie. Which would also be a great example of the male gaze.
This is a great example of undoing gender in a cover. Deadpool is posing similar to how women pose in movies and in Ads in general. It shows the idea of how women are often shown posing in odd positions because of it being “attractive” but when men are shown doing those poses it shows how ridiclous it is to have women look a certain way in the media.
