The lights are on
When I think of stop-motion animation, the first things that usually come to mind are wacky claymation shows like Mr. Bill or Wallace & Gromit, not high quality special effects and top notch fight choreography. This high octane short film by John J. (YouTube user counter 656), shows Cloud slashing robots while driving his signature motorcycle and engaging Sephiroth in a flashy, high-flying battle. A much-beloved FF VII character also makes her overdue return.
The entire thing is in Japanese, but it is definitely worth watching. If you've played the game you can probably deduce what's going on, anyway. Be sure to check out John H's blog post chronicling the behind the scenes of Final Fantasy VII: Stop-Motion. That's where I learned the tape over characters' joints towards the end of the film was to counteract loosening joints.
