The actor plays fireman Kev, who suffered horrific burns to his intimate body parts in the Sky1 drama.
“I was shocked,” he said. “I did the reading version of a double take: ‘What did I just read?’
“It was so bold to do that to the male protagonist, who spends the whole (opening) episode building up as a rugged survivor of something, then for them to do that. I was intrigued and blown away.”
He added: “We had to make decisions about what the injury actually was and look at images of people who’ve gone through this awful injury.
“The whole thing was a tough, tough journey, but that’s the reason why I wanted the job and wanted to play the role.”
The Smoke continues on Thursdays at 9pm on Sky1.
