I was lucky enough to find a whole lot of Doctor Who DVDs in a charity shop in Hereford the other day, so I've been watching a few which I'm sure I never saw first time round. One of them was Planet of Evil, in which a scientist tries to take anti-matter crystals from a remote planet, which starts killing the members of the expedition (or at least, the Creature of the Id a la Forbidden Planet does). The dark red jungle set was actually very impressive, but the story was a bit forgettable.
Then there was the Masque of Mandragora, with gorgeous Italian Renaissance costumes - Sarah Jane gets a lovely ball gown for the Masque itself (after nearly being sacrificed to a pagan god in the catacombs under the city).
But in both of those stories, apart from a few female extras in the masque scenes, Sarah Jane is the only woman there, and certainly the only woman with a speaking role. There's a black man on the crew of the space ship in Planet of Evil - and he doesn't die first! - but no other women at all.
