I learnt a blend of different martial arts - not in great depth, obviously - but various moves such as kicks, blocks and punches. It was all quite fun.

This medium that we're working in - film and television - for an audience, it's like you live through these characters because it's things you can't do in real life. Places you're not prepared to go in real life as a decent human being, anyway. Because if you're a conscientious person, so you live kind of vicariously through these people.

Obviously, it's not cable, it's streaming, but it's the same format. It's the same 10 episodes. It feels like cable as opposed to network.

So many directors these days direct by design and shoehorn you into things - direction or blocking - that they had in mind previously. They're short on time and they want to get that over with so they can get onto the finer details of a play.

I much prefer following a lead character that is doing morally questionable things. How much do you get on board? Do like that? Do you hate it? Does it matter?

I grew up doing plays - I went to a stage school after school - and it's always something that I've wanted to do, but, in a weird way, if you do television and film and you didn't go to drama school and don't have a theatrical background, it's hard to get your foot in the door. In the same way that it is for theater actors to get into television and film. There's a weird prejudice that goes both ways.
