yes, Steph....i do think it will be quite awhile before the final numbers can be reported on Ninja Assassin.
boxoffice.mojo (last time i checked) doesn't seem to be adding any new international figures, so i requested at a few Japanese blogs to maybe share their final figures with us. (i hope they do that).
some strange things, (to me anyway) are going on. in one Japan blog, yesterday, i saw that Ninja Assassin is availble on itune for .99 cents, even though it is still running in theaters there (i think until the 23rd of this month). hummmmm
then just before the March 16th release date, Netflix announced that the movie can be seen for a week free. hummmmm
but, we'll just have to wait at see what the end results will be.
