23 Actors You Totally Forgot Were In Doctor Who

23. Zoë Wanamaker

Now, don't stare! Zoë Wanamaker got tongues wagging when she was introduced as the self-proclaimed 'last human', Lady Cassandra O'Brien.”17 (that's just 'Cassandra' for short!), in Series 1's The End of the World but it wasn't until her subsequent return in Series 2's New Earth that fans got to see the actress on screen. A household name for her portrayal of Susan Harper in the long-running BBCs sitcom My Family, Zoë is an Olivier award-winning veteran of the Shakespearian stage who fantasy fans will also recognise as Madame Hooch from Harry Potter and the Philosopher's Stone.
