I'm loving the Sarah Jane Adventures, and just watched part one of this season's second story tonight. (And very intriguing it is.)
I was staring at the "madwoman" trying to work out why her face was so tantalisingly familiar--and it was Souad Faress who played Selma in Horizon on B7. No wonder I sort of recognised her: she has a very distinctive face, but it is 30 years on. Go, her! :-)
