And this week, in the busy Anthropoid, we get to see Dornan play one of the two Czech paratroopers who assassinated Reinhard Heydrich, architect of the Holocaust, in wartime Prague.
“They are absolute heroes in the Czech Republic,” he says. “You have no idea. This was the highest-ranking Nazi to be assassinated. How did I not know about this?”
So how did we get here? I assume that Dr Dornan would have preferred his son to enter a more respectable profession.
“I wasn’t one of those kids who wanted to be an actor when he grew up,” Dornan says. “But I got a real kick out of acting at school. I had to keep up appearances of being a rugby jock. Rugby was a big part of my life. I had to uphold that when round the boys. But, once in the drama studio, I unleashed another part of myself.”
