Helena Bonham Carter's villains
Helena Bonham Carter has joked she keeps being cast as a villain because she looks like a witch.
The 43-year-old, who plays the Red Queen in Alice In Wonderland, has already played evil characters in the Harry Potter films, Sweeney Todd and Big Fish.
She laughed: "I think it's the age, you know, that's what you get over 40, maybe - 'Ooh, she's aging. She must be evil. She looks like a witch.'"
She added: "I am playing lots of villains. It's horrible. Serial killer, sadist."
In the final two Harry Potter movies, due out this November and in July 2011, Helena takes her character Bellatrix's nastiness to new heights, including torturing Harry's pal Hermione (Emma Watson).
"Then Hermione gets to pretend to be me," Helena said. "I got to pretend to be Emma Watson pretending to be Hermione pretending to be Bellatrix. A lot of Russian dolls. It was hilarious."
