Joseph Gordon-Levitt admits in the new issue of Men's Health that the only reason eh cast Scarlett Johansson in his new film is because he's attracted to her:
"I didn't know Scarlett, but I spent more than a year with the image of her in my head playing this character. She couldn't not do this. Look, Scarlett is a gorgeous, gorgeous woman, but if you just compare purely physical features, plenty of girls are just as gorgeous. But she creates this extra something. It's in her walk, her eye contact. The total package is just off the charts."
Too bad she's engaged already now, Joseph. But wait, who knows. Hollywood marriages don't last.
