Here's a picture of Sabretooth (Schreiber) on set complete with battle scars and some freakishly long nails.

Bailey Chase told the Sunday Star Times of New Zealand that he's lining up an opportunity to play a role in the upcoming 'X-Men Origins: Wolverine'
"It's very confidential and top-secret. I think they're casting under alias names but for now, he's called Mr Yellow. He's about 30 years old, a charming southern guy on the surface but he's got some ulterior motives going on underneath. By the end of the film, he's probably not going to be such a nice guy."
Could this be Gambit?
