Just over a year after its second series aired, political thriller COBRA is set to return to Sky for its third outing.


The show follows senior politicians and crisis contingency planners ordering the response in times of national crisis.

The six-part third season, titled Rebellion, will follow the aftermath of an environmental disaster that has far-reaching consequences for Prime Minister Robert Sutherland, with Trainspotting star Robert Carlyle once again in the lead role.

Season one, titled COBRA, explored the effects of a huge solar flare which left much of Britain without power, causing social and political chaos, and was a big hit for Sky, launching to a cumulative audience of 2.2 million.

The sequel – COBRA: Cyberwar – also won praise for its addictive nature, and saw PM Sutherland's problems multiply as he faced a new, even more unpredictable threat: a series of devastating cyberattacks.

COBRA season 3 cast


COBRA fans can expect most of the regular cast to return for the highly anticipated third outing.

Robert Carlyle is returning as fictional Prime Minister Robert Sutherland, while Victoria Hamilton will be back as his Chief of Staff, Anna Marshall.

Speaking to RadioTimes.com in an exclusive interview back in October 2021, just days after the release of season 2, Carlyle said he hoped there's appetite for more COBRA after Cyberwar.

"Ben's currently writing an alien invasion script..." he joked. "He's not, he's not! But how do you up the ante? Who knows? But he's a fantastic writer, Ben, I'm sure he'll come up with something. Personally, I'd be very, very happy to do more, if they'll have me!"

Meanwhile, David Haig (Killing Eve), Richard Pepple (Gangs of London) and Marsha Thomason (The Bay) are also set to return for season 3, alongside Alexa Davies (Dead Pixels), Edward Bennett (Save Me Too), Lisa Palfrey (Chloe) and Lucy Cohu (Ripper Street).

In addition, Jane Horrocks (Bloods) has been cast in the role of populist Defence Secretary Victoria Dalton in the UK government.
