There are worse things in life than having Scarlett Johansson play your love interest in a movie – just ask Joseph Gordon-Levitt.
The newly engaged actress, 28, stars alongside Gordon-Levitt, 32, in his self-directed and self-written film, Don Jon.
“I didn’t know Scarlett, but I spent more than a year with the image of her in my head playing this character,” the actor tells Men’s Health. “She couldn’t not do this.”
Johansson’s sex appeal comes from much more than just looks, says the actor.
“Look, Scarlett is a gorgeous, gorgeous woman, but if you just compare purely physical features, plenty of girls are just as gorgeous,” he explains. “But she creates this extra something. It’s in her walk, her eye contact. The total package is just off the charts.”
But it isn’t just Johansson who Gordon-Levitt praises in the interview.
The star also shares love for his brother Dan Gordon-Levitt, who died three years ago at age 36.
