Makes me proud to be a Detroit native... or not.
I'd never heard of this Detroit Metal City manga before the live action movie was announced (there seems to be an anime in the works too), but according to ANN, KISS front man Gene Simmons is a fan and has a key roll in the film and former Megadeth guitarist Marty Friedman also plays in a short scene with Simmons.
I'm not exactly waiting in eager anticipation to see this one, but simply because it has "Detroit" in the title it does pique at least some interest. It'll be like... the Japanese version of 8 Mile!
A short teaser trailer can be seen below.
