The "Lone Wolf"....(mild spoiler)....

That was a very cool character. Kind of like the Harvey Keitel model "cleaner", but mixed in with a little of the Desh assassin character in the Bourne film.

He was only in this movie briefly, but made quite a showing. He should appear (as this character) in other movies. I know it would be difficult to cross-pollinate a minor character from one film (and that film's intellectual rights to the character) to another......but it would be a cool precedent!

Can anyone think of an example of when this has happened? (Obviously, I'm not talking about major characters popping up in other films of the same franchise, like Marvel movies).
