I was thinking exactly this. If i asked an artist to draw an image of irom man, i would bet that they would draw him in a famous pose, and they would try to draw his suit accurately or make it resemble a scene from the movie.

I would also bet that it would not be exact, line for line. Like they knew that there were buildings in the background. They knew his hand was up witht the light pointing at the viewer, they knew it was night time and they know what iron man looks like, maybe they used a few reference images to get the suit right but there would be enough differences that it wouldnt be exact. These images are slightly different than the movie stills and if made by a human they would look pretty similar to what the AI has done here. Especially if they were asked to draw a still from the movie like in this article.
