On a related note, why does every movie begin with several title cards for the studios and production companies? These are familiar and pretty much meaningless to 99% of moviegoers. Nobody chooses a movie because it was bankrolled by Paramount. Admittedly, as a cinephile, I have a few vague feelings about Dreamworks, Miramax and MTV Movies, but they never determine whether I see a particular film.
These announcements have zero marketing power, and only exist to stroke corporate egos. If the entertainment industry cared a little more about its customers, it would eliminate this useless wankery and get us to the stuff we paid for sooner.
