Here's one we weren't expecting - almost three years after it first debuted, Channel 4 cyber-thriller The Undeclared War has been renewed for a second season.
The new instalment comes from writer Colin Teevan (Das Boot), who wasn't involved with the first season, while Paul McGuigan takes over directing duties from Peter Kominsky (who remains an executive producer).
When it comes to the cast, Simon Pegg, Hannah Khalique-Brown, Alex Jennings and Ed Stoppard are returning, while Siân Brooke (Blue Lights), Danny Sapani (Black Panther) and Chloe Pirrie (Black Mirror) join the cast in new roles.
The synopsis for season 2 says: "Set in 2024, The Undeclared War returns with a fresh wave of tension and drama as the UK’s GCHQ grapples with the aftermath of a devastating Russian cyber-attack. Just when it seems the UK has gained the upper hand, the team uncovers a far more dangerous threat."

Interestingly, while the show started life as a show set slightly in the future, in picking up directly from the ending a number of years later, it will now be set in the recent past.
