Images of cardboard cut-outs to promote the movie have been revealed.
The summer 2011 movie is coming to DVD in spring 2012.
A short 16 second trailer for the movie has been released.
Saiyan Island writes "A new scan from Shonen Jump shows the prison hall Naruto will be put it Naruto Shippuden Movie 5: Blood Prison. There is also a thumbnail in the scan that shows the outside of the prison."
It's times like these I wish I lived in Japan.
