Last year, we saw intriguing hints at what a live-action 'Akira' movie might have looked like via some lovely storyboards by artist Chris Weston. Today we've got a whole batch of concept art from three separate iterations of the film, which is still waiting to get off the ground.

Props go out to ComicBookMovie for compiling designs from three different artists; evidently from the three separate versions that were prepared by directors Ruairi Robinson, Albert Hughes and Jaume Collet-Serra.

Here is a few vehicle designs from Tim Flattery, which ComicBookMovie believes was created for the film when Ruairi Robinson was attached in 2008.

The film's next director was Albert Hughes; here is work that Tommy Lee Edwards evidently created for his vision.

Finally, when Jaume Collet-Serra was brought on to the project after Hughes departed, artist Rodolfo Damaggio drew up some very compelling sketches for the Spanish director, who was the last director attached to the film.

Unfortunately, we may never see any of these sketches come to life, as the live-action 'Akira' is currently dead. Some would prefer it to stay that way; after seeing these designs, how do you feel?
