Simply put Helena Bonham Carter seems to get a very strange range of roles. In the very late Nineties she played Marla Singer in Fight Club, a suicidal messed up character who has no value to her life.
Since then she has hooked up with Tim Burton and worked on nearly all of his newer productions (usually along with Johnny Depp). Corpse Bride:
Not forgetting Charlie and the Chocolate Factory and Alice in Wonderland which is currently filming.
There is a definite link here with the dark films and then Tim Burton’s dark style to everything he does. What is strange to me is her casting in kids films / programs, like Wallace and Gromit Curse of the Were-Rabbit:
Lots of Harry Potter action too… all in all we love you!
