Fan Casting John Clark in Zack Snyder's Rainbow Six

A veteran CIA field operative whose body is a roadmap of scars and whose hands have done terrible things in service of his country. Recruited to lead Rainbow Six, he's a "one sharp blade" in a world of high-tech bullshit—a reluctant leader who prefers working alone but learns to trust his team. His only softness is his wife Sandy; his only remaining mission beyond the job is starting a family. Lethal, dry-witted, and haunted by the darkness he keeps on a tight leash, he's the man the world calls when the worst people need killing.
