Doctor Who: What Happened To Each Doctor After They Left The Show?
3. David Tennant
Last Regular Episode: The End Of Time: Part 2
The longest-serving modern Doctor, David Tennant said goodbye to the show on New Year's Day 2010, regenerating during the closing moments of The End Of Time: Part 2.
Since then, he's continued to be a presence on our movie and TV screens, with roles in How To Train Your Dragon, Ferdinand, Mary Queen Of Scots and Fright Night, alongside TV shows like Star Wars: The Clone Wars, Broadchurch, Good Omens and Jessica Jones, where he played Kilgrave, the show's sadistic, scene-stealing bad guy. He also launched a podcast in 2019, a chat show featuring guests like Jodie Whittaker and Jon Hamm. It's very good! Go check it out.
Most memorably though, he played the Tenth Doctor for an additional - and possibly final - time in 2013, starring in The Day Of The Doctor alongside Matt Smith and John Hurt. And he didn't miss a single step.
Unlike Eccleston, Tennant has remained open to the idea of stepping back inside the TARDIS at some point in the future, and it honestly wouldn't be a surprise to see him pop up in the impending 60th anniversary special.
