Michelle Trachtenberg as Kitty Pryde/Shadowcat
Not the most original choice but I've always enjoyed Trachtenberg's acting and feel she could inject some much-needed personality into the Kitty Pryde character that I felt Ellen Page lacks.If people ask what happened to Ellen, Logan did change the future so a lot of things changed. As an inside joke have Wolverine look confused when she introduces herself (due to the Weapon X program erasing his memory he has no memory of X1-3 Kitty Pryde).
Hugh Jackman as Logan/Wolverine
Obviously. Except we'll get the slice n dice Wolverine we want in this movie. No PG attacks just good ol' Rated R violence.
Takeshi Kaneshiro as Ogun
A ninja and martial arts master with past ties to Wolverine. The exact nature of his abilities are unknown despite being telepathic and being in peak physical condition.
Jamie Chung as Betsy Braddock/Psylocke
Introduced similar to Quicksilver in DOFP, Betsy is an old friend of Carmen that is contacted by Kitty. Knowing Carmen personally, Betsy assumes the responsibility and aids the two in their quest to resue her father.
Colin Farrell as Carmen Pryde
The father of Kitty Pryde and a talented scientist who is abrutely kidnapped by the Yakuza due to unpaid debts. Kitty and Wolverine set out on a mission to find him and rescue him.
India Eisley as Laura Kinney/X-23 (post-credits scene)
