Got introduced to Rufus Sewell in 'The Man in The High Castle'. He played an SS commander. Most intimidating and frightening presence on the screen - without raising his voice and no (direct) acts of violence. Great actor.
He is indeed an extremly good actor .. wasted in some earlier US productions that bought him in for the Shakespearean Gravitas (pissed away by poor scripts in Eleventh Hour) .. but a shining light in various UK productions such as Petruchio in ShakespeaRe-Told.
Two short seasons down, it's tight, it's sharp, it could go far.
