i don't know if this is quite what you wanted... but i saw the ad for the "5 free BRmovies on the back of the latest PSM magazine. i think you may have to clip the thing out and send it in with proof of purchase, or there should be some corresponding web site with directions on how to get your 5.
it also looked like there were only a select few to choose from, so it wasn't 5 movies from the entire library.
however, Blazing Saddles was one of the choices, so that's a bonus! :D
