With FX in particular, they've been fantastic and were really hands off. I mean, it helps that you've got Ridley Scott on your side.

Snoop [Dog] said [Peaky Blinders] reminded him of how he got involved with gang culture. It's always fantastically flattering when I see people dress like that and take on the look.

I like to create a character where you believe, deep down, that they don't really care if they live or die. That's very liberating for the character because, if the character is prepared to die, then they can do anything. It's impossible to stop them.

I think that helps because there has been no formality of friendship, the politeness of friendship, so we can just work directly on the work that's ahead of us [with Tom Hardey].

I wouldn't put myself in that bracket, but it's one of those things. I think what helps is that we [with Tom Hardey] don't socialize, we don't really know each other, we purely work together.

I think people are drawn to characters that break the rules. I think there is something about a good person doing bad things for what they consider to be a good reason. Then the battle is on to almost prove to the audience that it's justified. How far can you go with that? How far can that character go before people won't accept it? Trying to walk to edge of that line is a challenge.

I'm always interested in characters who are closed down, but who open up when they choose to, rather than when they're obliged to. I think that's a very appealing thing, for an audience and just in life. I like the idea that something will say nothing, and then get straight to the point. That feels like how your heroes should be.
