The masked antagonist has formulated a tangled web of deceptions through which he controls the actions of the other characters in the story.
To emphasize that fact and make the poster more interactive Amazon Prime Video released an image that had several small images that combined to form the image of the masked antagonist. What's even more fun is that if we zoom into the image we can see each of the characters that the antagonist controls.
Amazon uploaded the image with the caption: "zoom in to see who all he controls! #BreatheIntoTheShadows"
