Helena Bonham Carter went ''overboard'' with her 'Great Expectations' costume.The 46-year-old actress portrays eccentric jilted bride Miss Havisham in the forthcoming adaptation of Charles Dickens' classic novel and was excited to have input into the role. She said: ''I went overboard. I had this idea that her veil would grow over the years, like her grief. It's a bit pathological. Everything's a bit overgrown.'' Helena also admitted she was initially upset to be approached for the role by director Mike Newell because she is younger than the way the character is perceived to be. She said: ''At the start I was like, 'Huh. Already?' But Mike kept on saying, 'You're the right age!'' The actress also admitted she hated the way she was typecast as an ''English rose'' in the early days of her career as she didn't feel she suited the image. She added to Time Out magazine: ''I was never the wet and wilted Victorian ingénue. It was infuriating. I was young and shy.''
