Kouji Tajima the conceptual designer for many high profile projects like Captain Harlock, Les Miserables, Total Recall remake, Dragon Age, Garo and more, made a fan art movie poster of Attack On Titan, dating it for a 2018 release. This fan art poster, first posted on the the creator’s twitter account, created an uproar on the internet, reaching major anime news sites and blogs.
In a later tweet, Kouji acknowledges that he was inspired by the anime’s promotional poster, and expresses interest in wanting to work on the real movie poster. Perhaps he is hinting at TOHO, the company currently planning a Live-action movie of the same title.
Yes, there is actually a live-action movie project of Hajima Isayama’s Attack On Titan currently in the planning, it was announced to the public in December 2012. Despite some early set back with Director Tetsuya Nakashima quitting the project over a disagreement with the script writing team, and a delay in release date from Q4 2013 to 2014.
TOHO has yet to announced the demised of this project, and judging from the popularity of the anime series, I doubt it will be discontinued.
