Untitled Rainbow Six Project

I saw MI:2 and it wasn't too bad in terms of action, a really enjoyable and entertaining flick. The only problem was that he cast two gentelman that fought very awkwardly on film. For example, watch the last coreographed fight sequence between Cruise and Scott. It looks a bit too forced. Furthermore, Thandie Newton was a brilliant character and above all else had amazing sex appeal based on her hard ass attitude...

Anyway, I personally think Rainbow Six would be a tough film to direct due to the so called "cult" following it has achieved after the release of the highly acclaimed novel. The very first game was fantastic, yet the story slowly diminished to an action game genre, instead of preplanning and squad based strategy. But regardless, it's still a bad ass title. Everyone can thank Ubisoft for that. Although the new Splinter Cell does look extremely promising.

Okay, I don't want to drag this out any longer, sorry, but who do you think should be cast in this movie? And if there was to be a director change, who should take on the responsibility for this movie?

Obviously the most important Characters:
John Clark? Clarks Wife?
Domingo Chavez? Patsy (Clarks Daughter, Domingo's Wife)?
Alistair Stanley?
Price?
The Brightlings?
Jack Ryans cameo?
Popov?

then after:
Louiselle Louis, Deiter Weber and the rest of team Rainbow?

I'd love to hear everyones input on this, and thanks to everyone for taking out the time to read this post...
