(A Jean Marsh fansite)
Jean Marsh, whose long acting career is filled with brilliant examples of top-notch acting (and alarmingly frequent character death) is a British actress/director/writer of Extreme Awesome (this is like normal awesome, only more extreme). With credits including Doctor Who, Upstairs Downstairs and The Tomorrow People, numberless are the times viewers of her spiff have marveled at her characters’ complexity, costume, and eloquence, before shaking their fist in consternation as said character shuffles off this mortal coil.
Though the latter years of Jean Marshes’ roles have consisted primarily of deliciously evil roles, the trend of character deaths began even when she portrayed the sweetest sweeties ever to smile on this fine earth. This site bemoans the loss of sweeties and devils she’s portrayed over the years, while giving thanks that there are survivors amongst her filmography of characters.
