The actress told the Los Angeles Times she modeled her character’s speech after that of Hedy Lamarr, the screen legend and inventor who inspired Batman creators Bob Kane and Bill Finger.

(Hathaway also watched cat videos on YouTube to prepare for the role.)

Lamarr’s influence is apparent in the recently released second trailer for the film. Hathaway has just one line in the two-minute clip, but she draws it out for over 25 seconds, almost hissing the words into Bruce Wayne’s ear.

Hathaway also defended her somewhat controversial Catwoman costume in the interview: “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.” I can’t wait to see what purpose the pointy ears serve.
