David Tennant added line for Doctor Who regeneration

The surprise regeneration of Jodie Whittaker’s Thirteenth Doctor into David Tennant’s Fourteenth Doctor was one of the most exciting moments of 2022 for most Doctor Who fans. The culmination of a glorious BBC 100th birthday episode in the shape of The Power of the Doctor, the show brought us returning classic Doctors, companions and of course in the post-credits sizzler reel, our first glimpse of Fifteenth Doctor Ncuti Gatwa in costume.

The show also brought us an emotional exit speech from Jodie Whittaker and the first lines from David Tennant as the Fourteenth. But apparently, what David Tennant said came from him…

“It wasn’t exactly the longest day at the keyboard,” explained Russell T Davies to Doctor Who Magazine when talking about the process around the regeneration scene.

“They’re obvious first lines. But David added the bit about teeth. That’s his line. So it’s written by the two of us.”

He added: “That’s rather nice, isn’t it? I like that. I was really chuffed.”

Tennant’s line at the end of The Power of the Doctor saw him say “I know these teeth” in an apparent reference to his first line after regenerating from Christopher Ecclestone’s Ninth Doctor in 2005.

David Tennant will be starring in three one-hour long special 60th anniversary episodes of the BBC science fiction show in 2023 ahead of Ncuti Gatwa’s first full episode in the TARDIS during the festive season of the same year. This will be followed by the first full season of Ncuti Gatwa’s Fifteenth Doctor expected to air on BBC and Disney + in 2024.

The 60th anniversary episodes will be the first Doctor Who episodes since the BBC signed a new deal with Disney+ to be international distribution partners for the show, which it has been speculated will bring a great deal of extra cash to the show in the coming years.
