EXCLUSIVE: Scarlett Johansson Stuns at 'Ghost in the Shell' Premiere, Says It's Important to 'Push Boundaries'

By
Scarlett Johansson isn't afraid to push boundaries.
ET caught up with the 32-year-old actress at the New York City premiere of her new film, Ghost in the Shell, on Wednesday, where she dished on her sexy, glammed-up look -- and opened up about challenging herself on and off camera.
"I never really thought about my character as really having a gender actually, shes kind of a genderless, identityless, but it's important for me to continue to take on roles that I feel challenge me in some way," said Johansson, sporting a custom sparkly Balmain gown (similar to the one Paris Jackson wore to the GRAMMYs), Sophia Webster heels and Fred Leighton jewelry. 
"You know, [I] keep trying to push whatever boundary I set for myself, that's important," she added.

The mother of one kicks butt in her new sci-fi film, but the moves aren't just for show. She's also been taking self-defense classes.
"My trainer probably looks at me and is like, I'm this young and clumsy sort of block of wood he has to carve something out of," Johansson joked. "But he's actually here today, and he actually helped me train for this film."
As for whether the actress is ready to get back in the dating pool after her recent split from husband Romain Dauriac -- not so fast. But that doesn't mean she's flying solo to events.
"Oh, that's my brother. It's not really my date," Johansson laughed. "He just wanted a free ride over here, actually. He's like, 'Can I drive to the theater with you?' I'm like, 'Alright!'"
Ghost in the Shell hits theaters on Friday.
Johansson might not be ready to date just yet, but that doesn't mean she's not crushing on someone! Find out who she considers "the hottest guy right now in the world" in the video below.
