A group of fans are working in something called "Akira Project", and they opened a website to enroll people willing to participate in creating a Live Action trailer based on Otomo Katsuhiro's manga and anime masterpiece. This is the really short trailer for their project.
Description of the project in their website:
The Akira Project is a crowd-sourced, non-profit project meant to create a live action fan trailer of AKIRA, the renowned manga-turned-anime film from the late 1980′s; a stunning example of both mediums as art forms. While Hollywood is trying, for the fourth time, to complete a live-action adaptation of Akira, we, as fans, felt like we ought to take a shot at making our own adaptation. A chance to stick as close to the source material as possible. A chance to do Akira Justice.
We launched an Indiegogo campaign in July 2012 as part of a crowd sourcing effort to make this project come to life. Many people contributed not just financially but also with their time and talent to help the production that happened from November 2-5th 2012. It was an intense shoot with lots of adventures and hurdles, but we managed to get something amazing that will truly give Akira fans the world over something to be proud of!
The final edit and soundtrack of the trailer have been completed in June 2013. With the help of many artists both found locally and online, we are now creating the world of Akira and the special effects needed to make this trailer the best it can be. Starting October 2013, we will be finally releasing some artwork and behind-the-scenes material throughout the next few months, prior to the release of the trailer in early 2014.
