Michelle Ryan was cast as the Doctor's latest assistant in the first Doctor Who special.

Her name is Lady Christine and the press releases have described her as mysterious and that she intrigues the Doctor immediately.

The companion for the second Doctor Who special will be played by Lindsay Duncan. Duncan will play Adelaide, described by the press release as "the Doctor's cleverest and most strong-minded companion yet."

I thought there would be two specials this year, but according to the article that I posted at my journal, there are supposed to be four specials.

Lindsay will appear in the second of four specials (Michelle will appear in the first one called Planet of the Dead.)

If you ever want Doctor Who or David Tennant news, I usually post it to my journal.
