If I take my trusty videocamera and film myself kicking the Invisible Man's butt while you can clearly see a billboard advertising Coca Cola in the background, they can sue me for "Visual Representation of a Registered Trademark." Not likely. That is what is meant by a real world item. I am not claiming to be selling Coca Cola, or claiming to have anything to do with their company. I am representing the real world in a visual format. The distinction, "real world item", is very important. If it is something that is seen as part of the real world, and you represent it in art, you cannot be legally sued for anything. Can you imagine watching a TV program like "Sex in the City", with every billboard and advertising sign blacked out or blurred? No, because that is the real world. And a 3D animation falls under the same rules.
