The things you find when you wander around IMDB! (I swear, I can't even remember what I was looking up in the first place...) Apparently, That One Character from Doctor Who 4x06 isn't just Peter Davison's daughter--you see, he's married to Sandra Dickinson, who...played Trillian in the original HHGttG miniseries. Good god, man, that girl's got pedigree.
