There are Blood+ manga and Blood+ novelizations. The manga does not follow the anime very closely, and it is more bloody and mature. The novels follow the anime closely, but give more details and can explain things you can't explain in an anime.
The prequel novels for Blood+ have nothing to do with the movie.
well i meant as in it would be similar to the movie because the movie had prequel like qualities...
so besides the manga adaption, there is really no more story?
Well, the movie didn't have Hagi and the Blood+ prequels are set a 100+ years earlier and in Russia. I have heard there is even some BL hints with Hagi and someone else.
The manga adaption is loosely based on the anime storyline.
