I'm not a huge reader of Wolverine comics, but these characters seem to play a big part in what happens over yonder.
First off, here's the obvious, Hugh Jackman as Wolverine
Next, I think it's quite obvious that this bad-ass will be a part of the story I present Ken Watanabe as the Silver Samurai
Let's not forget the all important love interest. Here is Ziyi Zhang as Mariko
I think we could also work this character in as well, as the Silver Samurai has been involved with her, I give you Rhona Mitra as Viper/Madame Hydra
At the request of other fellow comic bookers, I have added a coupe characters that I probably should have been smart enough to add!
Here is Jet Li as Sunfire
Who didn't just love watching this chick kick some ass as Miho in Sin City? Here is Devon Aoki as Sunpyre
And finally, I thought that since we were in the neighborhood...kind of, we could throw in a villain just to throw a wrench in the spokes. I don't think it would be too hard to include him into the storyline. Afterall, look at what they did to the storyline in X-Men Origins: Wolverine. This casting took some real consideration and I think I've done pretty well here. I present Sean Bean as Omega Red
There you have it. Like I said, I'm not too familiar with this story, but I think I got the major players. If not, tell me who I missed and I will include them or go ahead and throw a name in!
