The ERIN BROCKOVICH star used hypnotherapy to kick his nicotine habit and he worried that his latest role as a 1940s cop would bring the craving for cigarettes back to him.
He explains, "I get to smoke hand-rolled cigarettes with a cigarette hanging out of my mouth. There will be a lot of smoking in Black Dahlia and I'm not a smoker.
"I smoked honey cigarettes, which are the herbal cigarettes. I don't recommend them because it's still smoke; I actually didn't have any craving for cigarettes after that because there's no nicotine in them, which is fantastic. It was cool."
