OK, I'll keep it simple:
There's a secret sect that fights evil- monsters, evil wizards, etc. In Japan, an agent, Heihachi Azuma, is investigating strange activity of aJ-pop producer. The producer is opening a new record company in America, so he follows him there. In America, he meets Gabe, a young guitar player who has latent powers.
This secret sect he belongs to- they all have superpowers, and they tap into it by playing music. The story is that music created the universe (Pythagoreas called it "the music of the spheres"), and if a certain type of person is good at it, they can become stronger, and faster, and can jump higher and greater distances. They all carry swords and guns- most of the organization uses katanas. Heihachi awakens Gave's powers, and circumstance forces them to team up.
I almost considered having the characters use a broadsword, but went with the katana so it wouldn't slow them down.
I try to poke fun at Asian stereotypes, such as spouting philosophy (Heihachi at one point tries to make a point using Eastern ideas, but makes a Star Wars analogy to get hsi point across). I originally started it intending to be very vicious to both Japanese and Americna pop music, but decided against it aftera guy I go to school with told me that J-pop stars are loved more than Americans love our pop stars.
before anyone cringes and thinks that Gary and Heihachi's relationship will be a typical Asian mentor/American protegee deal, I liken it more to Tommy Lee Jones and will Smith in "Men in Black."
One thing I do worry about is the notion that the members of the secret society are loyal to the organization before their country- which I supposed can be justified, as the secret society prevents the Apocalypse every few decades or so. And one more thing that I think might get me in trouble is the sword that Gabe uses- it was created hundreds if years ago in Japan, and was enchanted so that it would find its way into the hands of one with latent powers who would use it for good- a few years after it was created, it ended up in China. By the 19th century, it was in the possession of a Zulu warrior in Africa, and by WWII, had ended up back in Japan, in the possession of a prominent colonel. What ties these tow potentially controversial points together is the scene where Gabe's grandfather gets it- the owner of the sword always instinctively knows when to pass it on, and he ends up giving it to a captured American GI- Gabe's grnadpa- who he releases, and is executed for.
I think it wsa my exposure to Japanese cinema that made me realize how stereotyped American movies can be in their depictions of Japan, and this idea came up and I realized i could use it to counter those depictions
I want to do a good job, and for once Japanese may like how they are portrayed onscreen by an American movie. But I would still like advice on what else I can do.
I still feel a little guilty about having so many characters wielding katanas, but the opening scene in Tokyo, I hope, establishes a sense of normalcy so people get the idea that it is not normal for a Japanese person to even own a katana.
PS-I know the script sounds really strange. But I've got a strange imagination, so that's to be expected.
