Doctor Who stars Billie Piper and Christopher Eccleston are reprising their roles for a new audio series.
Eccleston, 60, appeared as the ninth incarnation of the time-travelling alien 20 years ago when showrunner Russell T Davies revived the sci-fi show.
I Hate Suzie actress Piper starred as his companion Rose Tyler and they filmed one series together before Scottish actor David Tennant took over Eccleston’s role.

A description of the new adventures says the Doctor’s past “returns to haunt him”, adding that “enemies old and new are waiting”.
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 (Productions), 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.”
Piper, 42, 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 on to 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.”
Doctor Who audios have been produced by Big Finish since 1999 and have featured actors including Tom Baker, Peter Davison, Tennant, Jodie Whittaker and Sir John Hurt.
