So today so the passing of Elizabeth Sladen, an English actress best known for portraying Sarah Jane Smith on Doctor Who (with the Third and Fourth Doctors). She had apparently been battling cancer for sometime (while continuing work on her Doctor Who spin-off The Sarah Jane Chronicles). Sladen was notable for introducing a new kind of companion to the show. A sort of emancipated woman type that shied away from the typical 'damsel in distress' character. And she was really hot.
