Which actor do you think seems the most bitter about their association with Doctor Who?
There's Eccleston, who we've all discussed repeatedly.
Then there's Lala Ward. I'm thinking she may be. She can't even be in the same room with Tom Baker. In DVD commentaries, she is derisive and hateful towards Matt Waterhouse, and when she isn't hating people, she seems bored.
Most of the other former stars seem to have enjoyed their time. But is there someone who hates it more than them?
