Well, I've been expecting this news ever since the Tim Burton Alice in Wonderland project was announced: Helena Bonham Carter will star as the Red Queen in Burton's fantastical tale. The surprising part (but not in a bad way) is the other new addition to the cast: Anne Hathaway. The Hollywood Reporter includes these details:
Hathaway is playing the White Queen, a benevolent monarch who is deposed and banished by her sister, the Red Queen (Carter), who has an affinity for crying out, "Off with their heads!" The White Queen needs Alice to slay a creature known as the Bandersnatch.
Of course Helena Bonham Carter fits right into this project, and I think the Hathaway choice is something of a pleasant surprise. What do you think?
