McQuarrie talks about his original script
"Well you know, it was an X-Men movie – it was a Marvel movie – but it existed very much in a real world. And more than anything, I love it for the very fact that – at least in the script I wrote – he was the only mutant in the movie… It was what you’d imagine the Wolverine universe to be under the control of somebody who wrote ‘The Usual Suspects’ and ‘The Way of the Gun’ and is a fan of Sergio Leone. It was Kurosawa’s Wolverine. There was a real romance to it, there was real humor to it, and a very straightforward sort of plain-faced brutality to it. I’m hoping they preserve that.
Hugh was really great, I liked working with Hugh a lot – he was very understanding, very open and supportive of me – so I’ll be very interested to see how that film turns out."
