UPDATE:  Two more names have since been added to the bottom of the list.

Back in October, we reported that a spinoff of the X-Men series was in the works.  The prequel, X-Men Origins: Wolverine, would explore the beginnings of Hugh Jackman’s storyline 17 years before the first movie took place.

Now four months later, we are getting a picture of how the rest of the cast is filling out.  It was originally rumored that Liev Schreiber would be playing a younger version of William Stryker (the role Brian Cox filled in X2).  That role actually belongs to Danny Huston (30 Days of Night).  But Schreiber will still have a presence in the film; he is now set to star as Victor Creed (a.k.a Sabretooth).

Here’s a list of the actors currently joining slated to join Jackman:

• Lynn Collins (The Number 23):  Kayla Silverfox
• Danny Huston (The Kingdom): William Stryker
• Taylor Kitsch (Friday Night Lights) Gambit
• Ryan Reynolds (Definitely, Maybe): Deadpool
• Liev Schrieber (The Painted Veil)  : Victor Creed/Sabretooth
• will.i.am (Black Eyed Peas singer):  Wraith
• Dominic Monaghan (Lost):  Barnell
• Daniel Henney (My Name Is Kim Sam-soon):  Agent Zero

The film is still scheduled for a May 1, 2009 release.
