From someone on the other board who supposedly read the script, the latest version I assume since Viper is mentioned:
Spoiler!!! Click to Read!:
Few thing to know about The Wolverine:
1) There are few villains: Shingen Yashida, Silver Samurai, Viper.
2) No mentions of mutants.Even Wolverine himself is not mentioned as mutant.
3)It is a modern story of a Warrior - Samurai without a past.
4)Wolverine is more vulnerable this time.There are few toxins that can slow-down his healing factor or kill him!!!
5)There is a different reason for Wolverine to go to Japan then in comics it based on.
6)Brutal Bear fight is there and it is better then in comics.Also, Canadian Hunters Bar fight is not skiped as it was in comics. 7)There are a Ninja Fight and ninjas are not acrobatic ********:thumbup:
It has neo-noir stylistic through the hole film.
Overall it is 100% better then X-Men Origins Wolverine which was illogical pig-poop that didn't fit into X-Men 1 and 2 at all.
