Christopher Eccleston said: "I am so happy to be back recording more adventures for the Ninth Doctor with Billie. I don't think my Doctor exists without Rose. He's a 'one man, one companion' kind of alien. We've explored him on his own at Big Finish, as a loner. But there's a resilience and a bravery and a deep empathy to Billie as Rose, that's why I do this. They complete each other."

Billie Piper added: "I can’t think of a better time for Rose to reunite with her first Doctor than now. Twenty years after she first ran into the TARDIS and towards adventure, here we are again, me and Chris, ready to have fun facing the universe – and the monsters – together." 

Producer Matt Fitton said: "Twenty years after the Ninth Doctor and Rose burst onto our screens, Christopher Eccleston and Billie Piper are back with that brilliant dynamic – the Doctor showing Rose the universe, and Rose showing him the best of humanity. 

"Across 12 episodes, slotting neatly into that 2005 series, we have more Jackie Tyler, more Powell Estate, plus friends and enemies old and new through time and space. Our writers have done an amazing job recapturing the spirit of that very special season, and Chris and Billie have embraced these scripts with delight and gusto. They're having a blast, back on that trip of a lifetime – and they sound fantastic!"
