We recently reported on a slew of casting additions to James Mangold's (Walk the Line) film starring Hugh Jackman in the title role.  Now it looks like a major player in the plot may have been cast.  Biel is reportedly being offered the role of Viper, a character often found conflicting with The Avengers as a high-ranking officer in Hydra, but one that has a complex backstory with Wolverine as well. Hit the jump for more on Biel's potential role.Twitch first reported on Biel's potential casting in The Wolverine.  Set to shoot in Australia this August, the film will also shoot on location in Japan.  Recent casting additions have included a generous amount of Japanese actors in pivotal roles, at least according to the source material (Chris Claremont and Frank Miller's arc).  Viper, or Madame Hydra, is said to be of Eastern European descent, which Biel can pull off.   The character's association with Wolverine is complex, involving a forced marriage through blackmail, mortal wounds due to spirit possession and, believe it or not, even actual emotional attachment.  This arc would fit in well with the web of betrayal and heartbreak laid out by the other characters in Claremont/Miller story.Biel can next be seen in the Total Recall reboot starring Colin Farrell, followed by the horror mystery, The Tall Man.
