Kishimoto's full time job is writing his manga, Since Kishimoto isn't going to take a break from writing to storyboard a film, the movie won't be made with his influences - and the creative team who makes it isn't going to write ANYTHING that might contradict later plot revelations.

Basically, unless more films are made after the series ends, nothing is going to be made as direct supplimentary material.
in 10 minutes i could come up with something 100 times better than the last filler arc/movie (which leads me to believe they have 5 year olds making filler scripts), and i'm sure kishimoto could do the same. he can take a break for 3-4 hours to write a small script and some concepts, he doesn't even have to draw anything. its not like all he does the entire day is draw manga.
