Helena Bonham Carter broke through in the eighties with her role in Lucy Honeychurch in the Merchant-Ivory film A Room With a View, and she was soon cast in other "English rose" parts.
More recently, she played Queen Elizabeth (not the current queen of England, but rather, her mother) in the King George VI biopic The King's Speech, which earned her a lot of award nominations . . . and awards.
In between she played a lot of quirky roles in movies directed by her boyfriend, Tim Burton.
