It takes a lot for the gangs in Gangs of London to be shaken – but Zeek, a mysterious new figure on the streets, certainly succeeds.

Working from the shadows and with unknown connections, Zeek achieves in rocking Elliot and the Wallaces to their core with his unmatched hand-to-hand combat and fighting skills.

But there’s more to Zeek than just some silent assassin for hire. He’s a man on his own mission… It's just a case of figuring out what that is.

Speaking ahead of the series launch, Andrew Koji talks about joining the series, what Zeek’s true motives are, and how his own history of martial arts came in particularly handy.

It’s been a very interesting show. Season one was very groundbreaking in terms of British Action TV and cinematic action scenes, which I think has never been done before, and influences from Asian cinema. I think it’s always been a very interesting show with a mix of characters, a mix of drama and action. There’s nothing else really like it on British TV.

It’s really kind of a whodunit mystery in two parts. One storyline is the spiking of the cocaine killing hundreds of people throughout London, trying to find out who and why. The other is figuring out who killed Elliot’s wife and child.

Zeek is an outsider, and he’s been hired to track down Sean Wallace, but we don’t know who’s hired him, and we don’t know why. There’s actually a lot more going on with Zeek, as we’ll find out. He’s a bit enigmatic, but we find out throughout the season that there’s more than meets the eye. And there’s more going on beneath the surface. Zeek is a bit of a lone wolf, an assassin who’s got a bit of a mysterious past that will also be unravelled throughout the show.

He is driven by jealousy, ambition, revenge and a whole lot of anger and pain. He’s like a lost child. A puppy just wants to be loved. But deep down, he’s too scarred because of that. And so he won’t let anyone in. He’s an avoidant, dismissive attachment style, for sure.

Hong Sun’s a character. He’s a real unique, quirky, fella, and I think he brings a fresh filmmaking style to an essentially English TV show. His Asian influences and sensibility from making films in Korea is something I think that hopefully he injects into Gangs of London season three and spices it up a little bit.

Zeek’s fighting style is a mix of everything. I think he spent most of his life training, getting beaten up, dealing with his emotions through fighting. He is very street style, MMA, brutal, efficient, not very nice. I also think he’s someone who’s used to pain. That’s his world. And so he’ll do his best to invite his prey into that world if need be.

In episode six there is a pretty intense fight between Elliot and Zeek. They finally come clashing head-to-head, and they fight throughout an abandoned children’s home, which could probably very well be the home that Zeek grew up in himself.

It was filmed over a period of maybe three to four days. Separated in different places. There’s a sequence which had a lot of moving parts going on, and then after they crash through to the bottom of the floor. Two opposing forces colliding together, with slightly different intentions, motivations and styles.

Elliot is essentially losing control and has lost control throughout the fight because he thinks that Zeek is the one who killed his family, so he’s fighting like a wild animal. So Zeek is, in a way, defending himself, essentially, because he’s not quite sure if he really wants him dead.

Zeek is a bit of a strategist. Beneath the veneer of his image, where he might come across like this single-minded, cold-hearted assassin, he’s actually quite smart, and maybe he might be better off as an ally or someone who at least owes him something for season four. It was a pretty intense sequence to shoot. A lot of fun getting to dance with Sopé.

I’ve done a few action things by this point, so it helped a lot, and enabled me to try and find the character behind the fight, and also with the technicalities of doing a fight scene for TV.

It was a nice leather jacket. I might ask somebody actually. They should give it to me, really, shouldn’t they? Pretty nice jacket. Strong shoulders.

Unpredictable, explosive and visceral.
