Yes, which is why I should have recognized him in "Harry Potter."David Tennant is also The Doctor in Seasons 201, 301 and 401 of Dr. Who.
I neither have nor want Amazon Prime.Now streaming on Prime for free. Seasons 101 to 1001.
Mine is Jodie Whittaker.Tennant is my favorite of the "new" doctors
Seriously, I've seen them all, from William Hartnell through Peter Capaldi and John Hurt, and I've loved all of them, but for a very long time my favorite was Jon Pertwee. But when I saw that gorgeous announcement about Jodie Whittaker (which she totally nailed) I fell in love all over again. It's been obvious for a very long time that time lords could change gender when regenerating (I believe Ramona did it, in fact, though her regeneration method was totally non-standard), and the last few seasons have been building up to it, what with both Missy and, um, was it Lord President Rassilon? in "Hell Bent" (episode 12 of season 9, 2015 - Hell Bent (Doctor Who) - Wikipedia).
I'm very much looking forward to October, when the new season (presumably) begins.
