Peter Mullan has said he doesn't care whether or not viewers sympathise with his latest TV character.
The Glaswegian actor plays a Brighton crime boss who gets Alzheimer's in Channel 4's four-part drama The Fear.
"You can feel empathy yes, but sympathy? You shouldn't care two hoots if I'm being honest," he said.
"I mean, you're looking at a guy who's been running a drug empire for years, he's killed people to get to where he is and he wouldn't think twice - in the past - about the number of lives he has destroyed through the so-called illegal product that he sells."
The actor's film roles have included Braveheart, Trainspotting, War Horse and Tyrannosaur.
And he says the key to success is getting to know his co-stars.
"The more you get to know someone, the more horrible you can be to them in a scene because you trust one another," he said.
"Then you can have fun and just play."
:: The Fear airs over four consecutive nights on Channel 4, starting Monday, December 3.
