In the series, which was filmed in Cape Town, the 1.96 metre tall Hopper plays Billy Bones, alongside Toby Stephens' Captain Flint, Luke Arnold as John Silver, Hakeem Kae Kazim as Mr Scott and local actors Sean Cameron Michael as Richard Guthrie and Louise Barnes as Miranda Barlow.

Media Update caught up with Hopper in between filming to ask him a few questions.

You've just completed filming the third season of Black Sails, but this is the first time we'll see it in South Africa...

When I tell people about it, it sounds like I am just going to work and having a laugh on a pirate ship because no one has seen it here. So it’s really exciting that it’s finally being shown in the country in which it was filmed.

What is Black Sails about?

It’s about the golden age of pirates. It uses characters from the book Treasure Island but is set 20 years before the book. So we’ve got Long John Silver in there and Billy Bones, who I play, along with real pirates who existed. It’s got everything you could want from a pirate show and it's about what pirates were really like.

How much time did you spend filming at sea?

None. We filmed in a studio in Cape Town where they have huge water tanks and the ships are in them. We are always on water but we are in a tank and surrounded by a green screen, so we are never out at sea. There’s a machine that creates the wave effects and the whole ship moves like it’s on the ocean.

Did you have to do any pre-filming training?

Yes. Before any of the cast got in front of the camera we were put through an extreme pirate boot camp that involved a strict regime. It wasn't just the rope work and rigorous exercises that tested us though, it was the diets which was an even tougher thing for me.

Would you have survived in the pirate world?

Hell no. It was brutal and although I enjoy acting in that world, I wouldn’t have enjoyed living in it. I loved filming the action stuff, though. It can get pretty violent at times but that's the world these guys lived in. We wanted to show historically what a violent, brutal world it was. Men and women died all the time. It's a world where you're constantly struggling to survive.
