I cannot help you with a script or with lending my voice to your movie (unless you need someone with a heavy german accent), but try to work with low-poly figures for a movie - they render faster, and won't choke down your system. Try to work with maps instead of real geometry wherever possible, avoid ray tracing for more speed and a lighter load for your system.
