the opening i'm gonna use is the one from Akira - a classic animation masterpeice by Katsuhiro Otomo.

i couldnt get a link but here is why i like it:
-amazing attention to detail (considering it was animated by hand) e.g. physics, reflections, fire/water..
-brilliant music. very japanese > it completely goes with the tribal biker gang aspect of the movie as well as it's dystopic take on life in the future.
-it reminds me slightly of mad max but also blade runner in the fact that it is shown at the beggining that it is post-apocalyptic (common for manga films > often set in neo-tokyo)
-great editing and special effects really make visualization of speed far more entertaining and action packed.
