Cameron Diaz reveals how she prepared for latest movie role

Cameron Diaz had to get “really smart” to prepare for her role in new movie The Green Hornet. In the superhero flick, the Hollywood actress plays the Green Hornet’s (Seth Rogen) assistant Lenore Case, who is the brains of the operation.

“I had to get really smart before the movie started,” Cameron said.

“So I trained myself to be smart for a couple of months and now I’ve totally forgotten about it.”

Diaz recently revealed that she has no interest in directing or producing films — because her ADD means she wouldn’t be able to concentrate on behind-the-scenes work.

“I have no interest in directing movies or producing movies,” she said.

“I like my role in making films. It’s the perfect amount of involvement for me. I have ADD. I would never be able to spend two years making a movie or even one year. I would just, I’d be someplace else within a few short moments.”

ADD stands for attention deficit disorder, which can make many sufferers unable to focus on one task for a prolonged amount of time.
