Grabbed this from Bleeding Cool:
Based on the celebrated comic book arc, The Wolverine finds Logan, the eternal warrior and outsider, in Japan. There, samurai steel will clash with adamantium claw as Logan confronts a mysterious figure from his past in an epic battle that will leave him forever changed.
The Wolverine is set for release on July 26 2013.
And in other Wolverine movie news, Yun Lee has been cast as the Silver Samurai and they're looking to cast Viper as well. Here's hoping they draw upon the source material in the Wolverine limited series and Uncanny X-Men #172-173.
