Doctor Who star David Tennant denied rumours he is planning to quit the role next year at the premiere of the show’s Christmas special.
Questions arose about Tennant’s future in the BBC1 series after new assistant Catherine Tate told the Jonathan Ross show she thought the next series would be Tennant’s last.
Speaking at last night’s premiere of Doctor Who: Voyage of the Damned, Tennant dismissed the claim as "a load of old nonsense".
"Catherine Tate stitched me up good and proper. She goes on Jonathan Ross and makes up a load of old nonsense," he said.
"Unbeknownst to me, she thinks I’ve made a decision – she’d clearly had too much coffee that morning.
"She said I was leaving, which was a decision I haven’t made yet. Maybe she’s made it for me, but I’m going to keep people guessing for as long as possible.
"I’m doing four more specials and beyond that no one’s asked me to make any decisions and I’m quite happy to be enigmatic for as long as possible."
Kylie Minogue guest-stars in the Christmas Day special as Astrid Peth, a waitress on board the Titanic, who shares a kiss with the Doctor.
Kylie said appearing in the one-off episode was "an incredible thrill".
It also features Geoffrey Palmer as the Captain of the Titanic and Rita, Sue And Bob Too star George Costigan as baddie Max Capricorn.
Tennant said: "It’s a very odd and slightly bewildering sort of thing to be in the middle of, but it’s something that it’s very easy to be genuinely excited about.
"I really love it and even if I had nothing to do with it, I’d be looking forward to the Christmas special, so it’s a privilege to be in the middle of it all."
The 10th doctor has drawn praise from wide quarters after he replaced Christopher Eccleston in 2005.
Doctor Who writer Russell T Davies said: "I’m delighted with the next series, we’re doing stuff we’ve never done before and it’s bigger and better than before.
"Everyone is marvellously making a fuss about Kylie, but it’s because David Tennant’s in it. That’s what I love about this show most of all. He’s literally Britain’s finest actor, I honestly to God think that, so when you’re writing for him you want him to do anything and go anywhere and he’s capable of anything, and you want to push him as an actor so that’s what we try and do and he’s brilliant."
Davies confirmed that Tennant was "absolutely not" quitting the Tardis.
The special was screened last night before a celebrity audience at London’s Science Museum.
:: Doctor Who: Voyage Of The Damned is on BBC1 on Christmas Day at 6.50pm.
