Perfect fit to play the character....

Harley Quinn... if the folks in the movie industry would stick to the comics like they should and bring in all the characters from those batman comics.

She would fit the character's looks and physique perfectly in my opinion! She's white, has the pretty face, large breasts, little'ish waist, nice big hips, and nice legs. All she'd need to do is keep the quirky/wacky voice from TBBT and add-in the crazy, yet innocent, sadistic, evil tendencies and she'd be a winner! Who else agrees?!?
