Gary Oldman as Jackson Lamb in Slow Horses is perfect casting. But if Oldman had been unavailable, who else could have killed in that role?

My own nomination is Ralph Fiennes - his Lamb would have been a bit more posh, but just as scathing.

EDIT: Jared Harris, Tim Roth and David Thewlis would all be great. And Frank Stallone, obviously.
