Anne Hathaway is pleased that everything in 'The Dark Knight Rises' has ''a purpose''.
The 'One Day' actress - who portrays Selina Kyle, Catwoman, in the upcoming third and final movie in the Batman franchise - explained nothing in director Christopher Nolan's concept of Gotham City was put in place just for "fantasy's sake".
She said: "I love the costume because everything has a purpose, nothing is in place for fantasy's sake, and that's the case with everything in Christopher Nolan's Gotham City."
The 27-year-old star also admitted after being cast in the role, she researched the history of the legendary character by reading the traditional comics in which Catwoman first appeared.
Anne added in an interview with the Los Angeles Times: "I really got into the comics after I was cast and I like that when she made her first appearance she meets Bruce Wayne and says 'Let go of me or I'll claw your eyes out,' and he says, 'Careful, claws in or papa spank.'
"So I'm glad we've come a long way since then."
