At a Repo Men press conference today, Liev Schreiber confirmed that Hugh Jackman has read the Wolverine 2 screenplay. Even though he's unsure whether Sabretooth will appear, he's gung-ho to make a comeback during Logan's Samurai saga.
At a press conference for Repo Men in New York, Schreiber had the following to say about Wolverine's Japan odyssey.
I just had dinner with [Hugh Jackman] last night and Hugh read the first draft of the script and I was really excited about it. It's still not clear whether or not Victor will be present in the Japan storyline. In the Japan storyline as I remember it from the Wolverine comics, Victor wasn't there. So I don't know, of course I've got my fingers crossed because I love the character so much, to have the chance to do it again would be a lot of fun, but I'm not sure.
Wolverine 2 is slated to film early next year.
EDIT: Hugh Jackman has read the script, not Schreiber as previously reported.
