You may remember Pam Ferris as the scary Miss Trunchbull in Matilda, or the equally scary but funny Irish mob leader Tommy Cotter in last year's Death to Smoochy. And next year she'll be portraying Harry's scary Aunt Marge in Harry Potter and the Prisoner of Azkaban. Perhaps it's no coincidence all these roles have certain similarities, as Pam explains in her interview with The Mirror.
"Apart from gardening, cooking and drinking good wine with my husband and friends, what I like best is playing grotesque women.
"I love every kind of grotesque - scary ones, fat ones and vicious ones. They're really good fun.
"I think the profession has changed a lot since I entered it. It's much more personality-led now rather than acting-led. But I happen to be part of an old school that believes in transformation.
"If you're part of that school, you go for the artistic satisfaction at the expense of paying the bills. Rather than earning a stable living being the same person, I've made myself as versatile as possible. And I wouldn't change a thing."
