Russell Tovey and Emma Thompson star in new series Years and Years.

The new six-part BBC drama, which is helmed by Queer As Folk and Cucumber creator Russell T Davies, follows the fictional Lyons family over the course of 15 years in a Britain rocked by unstable political, economic and technological change.

“I’ve wanted to write this for 20 years or so. And as the world accelerates like crazy around us, I realised I’d better get on with it,” said Davies. “It’s a joy to be back home with RED, and an honour to be on BBC One.”

The trailer includes a first look at Tovey’s character Daniel Lyons, who is seen kissing his husband Ralph on their wedding day, and Oscar-winner Emma Thompson as Vivienne Rook, an outspoken celebrity turned political figure who divides the nation.

“What sort of world are we in? If it’s this bad now, what’s it gonna be like for you in 30 years time? 10 years? 5 years? What’s it gonna be like?” asks Tovey’s character in the trailer for the show.

Joining them are Rory Kinnear as financial adviser Stephen Lyons; T’Nia Miller as ambitious accountant Celeste; Jessica Hynes as secretive radical Edith; Ruth Madeley as heavily pregnant Rosie; and Anne Reid as Muriel, imperial grandmother to the Lyons.
