ROTTEN TOMATOES, the same site that managed to compile over ONE HUNDRED REVIEWS for PAUL BLART: MALL COP, found a whopping three for NINJA. Three!
BoxOfficeMojo doesn't even have a listing for it.
Despite having apparently been bit in the ass by its own mastery of the ninja art of invisibility, NINJA must have made some money somewhere, because a sequel is on the way from Nu Image films.
The original NINJA was about an American orphan who is adopted into a martial arts dojo in Japan, trained in Ninjitsu, and sent to New York to retrieve a legendary armored chest containing the weapons of the last Kōga ninja. Scott Adkins played the lead, and moviehole reports that he will be reunited with original director Isaac Florentine for the sequel.
NINJA 2, is due to start filming early 2013.
