Your ship is at the bottom of the English Channel, your crew are probably dead, and your nearest source of food is in a Loch six hundred miles away. And the natives are insane.

Deborah Watling is best known for her role as Victoria in Doctor Who, alongside the second Doctor, Patrick Troughton. But many people aren't aware of her extensive acting career on stage, film, and television. Born into a theatrical family, her first on-screen roles were as a child in William Tell and episodes of The Invisible Man. But it was her role as Alice in The Life of Lewis Carroll that brought her to the attention of Doctor Who producer Innes Lloyd.
