David Tennant has said that the stakes are higher than ever for his final Doctor Who episodes. The actor will feature in one-hour special ‘The Waters Of Mars’ on November 15 on the BBC, with the following two-parter ‘The End of Time’ featuring his character’s death and regeneration as Matt Smith.

Tennant told BBC Newsbeat:

“Because you can only tell the story of a character dying once it allows you to go to places you haven’t quite been before.

“It allows you to tell types of stories that you can’t do when it’s an ongoing series. It allows it to be bigger and more epic, and sadder and wilder, and the stakes are just that bit higher.”

Actor David Harewood previously revealed that Tennant’s final days of shooting on the show were emotionally charged, with people “in tears” on set.
