Was any of the movies based off anything from the manga? In regards to the Bleach Movies (Memories of Nobody, Diamond Dust Rebellion, Fade to Black and Hell Verse) were any of them based off anything from the Manga? or are they just as much filler as the Bount Arc?
Speaking to two of those movies, I don't recall any distinct plot-advancing points within them.  They explored some different concepts related to the Bleach universe (such as "Blanks" in Memories of Nobody, and the King's Seal in The Diamond Dust Rebellion), but to my recollection, there wasn't anything that was specifically canonical that the movies were based on.
