Anyways, can't the movie just have a nice Star Warsian scrolling intro that repeats all of the above gubbins? There is the slight problem of the following, tho, even if it seems to relate to video games / animation rather than live action:
The video games that our licensing partners have created have done an incredible job of bringing the Warhammer and Warhammer 40,000 games to life, and we appreciate that hobbyists may even want to make movies based upon our intellectual property. Unfortunately, due to the nuances of the law in some territories, we cannot allow any unlicensed movies to be created which are based upon our intellectual property. "
