Here's part 2 of my interview with "Doctor Whorecurring guest star Alex Kingston. (Part 1 is here.) Because Kingston's a bit older than Matt Smith and Karen Gillan, the original "Doctor Who" series was an actual part of her childhood, and we talk about that, River Song's unique position among the history of the Doctor's companions, and more.

Enjoy. Back tomorrow with a few words from Amy Pond.
