DOCTOR WHO stars Billie Piper and David Tennant told fans how much they loved filming in Cardiff as they switched on the city's Christmas lights last night.
The ceremony was marked with a spectacular fireworks display, which delighted the thousands of families who turned up to watch.
The actors led the countdown to the big switch on.
Piper told the crowd, "Cardiff is like my home town now - I have been here for about two years. We have the warmest welcome wherever we go, it's been really lovely.
"You have been so generous, giving up your streets and restaurants for us to film.
"It's all been great, we're having such a great time here at the moment, everyone is being so nice and so friendly."
Tennant said, "I'm having a great time in Cardiff, it's such a nice place and it's quite overwhelming to be here."
Tennant is the 10th Doctor and he made his first appearance, taking over from Christopher Eccleston, in the final scene of the last series, penned by Swansea writer Russell T Davies.
"I'm having a miserable time - Max Boyce is taking over as the new Doctor," he joked, before adding, "I'm having a ball, I get to hang out with Billie Piper, it's a great time.
"Every day is different, the other day we were hanging 30ft in the air, although I can't tell you why."
Before the Doctor Who actors arrived on stage the audience were entertained by the BBC's Derek Brockway and Claire Summers.
