Tim Roth as Archibald Cunningham in Rob Roy- just wow.
Not mention he plays Cunningham with an incredible level of flamboyance and menace.
Cunningham is the kind of guy who appears to be very handsome, even angelic on the surface but in reality, he's a cruel, dangerous sadistic demonic/devilish man who's only interested in himself.
He's also not afraid to get his hands dirty and in various duels, is known for giving off the impression he's a harmless target, a clueless idiot but that's just an act.
He enjoys toying with his victims, his prey, prolonging their suffering before ending their lives in a single moment.
Cunningham keeps his true self hidden, buried underneath layers of clothes and wigs but when there's no other choice and if his opponent is someone he needs to give his full attention to, he'll remove his wig, discarding it which reveals he's getting serious while allowing his seemingly harmless flamboyant personality to fade away, replaced by the real man: a vicious, aggressive psychopath who according to Roth himself is also a skinhead.
