Have you never seen Silence of the Lambs?
Nope, Looking him up on IMDB, I've seen
Mission Impossible II (which his must have had a very minimal role in, since it says that he was uncredited),
The Mask of Zorro, damn... that explains why Zorro was the only movie that I could think of, it's really the only one I've seen... I was sure I'd seen more, pretty sure I own
Fracture, though, but I've never watched it.
I don't recall seeing any warrior-ish description of Langtry in the books. He just looked like the wizard's wizard, IIRC.
Not in his physical appearance, or during any of his screen time, but you don't throw up wards to fend off vampires and Outsiders on the fly while retreating though the Nevernever without some pretty good skill in combat magic.
Not sure where this falls in the conversation, but when I close my eyes, I see Kurt Russell as Michael, Will Smith as Sanya, and Pat Morita as Shiro.
I think that Pat Morita as Shiro was discussed before with general approval, but his being dead was a bit of a problem.
Will Smith as Sanya... I don't know, I really don't think I could take him seriously with a Russian accent. Although I do recall Jim saying (presumably jokingly) that he though Will could pull off Harry personality well, but that he'd need to lose a fair bit of muscle.
