Drew did two different backgrounds for this artwork for the obvious reason of different usage. He originally painted the one sheet and subsequently the studio wanted a change of proportion for other usages.
This is another example of a first. After Drew did this piece it became a standard way to depict an action hero in movie advertising. A big guy with a gun became the only way to compete with this image. It still remains the quintessential action hero image. Could that be because it illustrates not only the image of a powerful individual but Drew's depiction also captures the spirit of the man and his struggle?
