Kenn I have thought this for a long time. Not just about dollys, but movies also depict alien visitations, same way action shoot-em-ups often depict Americans Killing Arabs or a Black man dying in the first 10 minutes. Why do some film industry corporations have particular symbols: Warner Bros with their Shield in the sky, or Fox Studios where the search lights never touch the words, or Columbia Picures where the lady hold the torch usually in front of the 'U'... is their relevance to their sybolism related to that of the genre of films they create?

Why do Warner Bros have a shield in the sky? Like a police badge? what are they enforcing through motion picture? Are they above the law as to why the shield is in the clouds?
How come Fox Studios are never illuminated by the search light according to their logo? We see them but the search light doesn't pick them up.. And Columbia Picture...

What it gotta do with Alien Conspiracy? hummmm...
