...well, not really. I just concluded a very satisfying viewing of the Golan-Globus ninja flick Enter the Ninja. My lovely wife didn't show much interest, especially since she missed the opening ninja-training scene. There are really only two scenes of what you'd call traditional ninja fare--guys with masks and ninja suits sneaking around--and they bookend the film, with the middle part being largely standard chop-socky film stuff: Franco Nero and his mustache, having graduated from ninja school by proving he can kill a whole platoon of red-shirts (they target ninja really do wear red uniforms) out in the jungle withour getting a speck of blood or dirt on his sparkling while ninja tunic, goes to hang with his friend in the Phillippines. This worthy--an old army buddy, natch--owns a plantation that's sought by greedy land barons with thugs who chase away his workers, etc etc. There's also the obligatory unsatisfied wife just dying for a touch of that ninja lovin'. The film's climax is pretty neat, as ninja film veteran Sho Kosugi (wearing traditional black garb) and fight coordinator/stuntman Mike Stone (who also wrote the original story) face off in a duel to the death in a Manila sport arena. Tasty stuff.
I plan to write a review, but in the meantime you can chew on this lengthy examination at Teleport City, which provides lots of juicy history not only about ninja movies (key quote: "When your two best entries in a genre both come from Cannon Films, you're in trouble.") but their real-life inspiration. Check it out.
