CHUD is reporting that Liev Schreiber is playing Victor Creed (aka Sabretooth) in the Gavin Hood-directed X-Men Origins: Wolverine and not a young Stryker as was previously believed.

The site adds that Michael C. Hall is instead in talks for the role of Stryker and that they are eyeing Michelle Monaghan for Silverfox.

Leading up to the events of X-Men,” Wolverine tells the story of Wolverine’s epically violent and romantic past, his complex relationship with Victor Creed, and the ominous Weapon X program. Along the way, Wolverine encounters many mutants, both familiar and new, including surprise appearances by several legends of the X-Men universe.

The movie opens in theaters on May 1, 2009.

Here’s the Michael related mention from CHUD:

So who is playing Stryker? Nobody is set yet, but the producers are darkly dreaming Dexter, if you get what I mean. Meanwhile the rest of the cast is still in formation, which means that the producers are hunting folks down - one of the names that’s on the top of their list is Michelle Monaghan for Silver Fox. I’ve heard a lot of names attached to this one over the weeks - and reported some of them - and I know that there’s another high powered actress that’s on the list as well, so nothing is set in stone. But as I always say, the casting wish lists tell you a lot about what the filmmakers are striving for, and a Wolverine movie featuring Michael C Hall, Liev Schreiber and Michelle Monaghan is a damn well cast Wolverine movie.
