Steve Jobs was an innovator, who gave the world the iPad and the iPhone. But Jobs was also a passionate man, one who was known to be very demanding in his younger years.

Ashton Kutcher, 35, who played Steve in the upcoming film "Jobs," admits that he has a desire to "be liked a little bit more than Steve did" and was happy to shed that aggressiveness within his character once filming wrapped.

Kutcher, who went method for this role, eating the food Jobs ate (which landed him in the hospital), walking the way he walked and reading the books he read, spoke to ABC News last night at the NYC premier for the film.

"[Steve] was a very passionate guy, who was on edge," Kutcher said. "Putting yourself on edge, being a volatile person is really scary because when you become that reactive and that volatile, you don't know what you're doing in the moment of that level of volatility and so allowing yourself to be okay with that is pretty scary."

The former "That '70s Show" star, who is dating his former co-star Mila Kunis, said losing that "volatility" was important for all the people close to him.

"You become slightly unpredictable as a human being," he added. "And for the people around me, I didn't want to maintain that."

Kutcher was also glad to stop walking like Jobs, which he said was "kind of painful."

"When you start walking a different way, your body doesn't know what you're doing," he said. "It'd be like putting skis on a car and assuming that car's going to drive the same way. The suspension might get a little messed up. So that was nice [to get rid of]."

Aside from his suspension being a little off, Kutcher respects, admires and loved playing Jobs. But this movie hasn't made him question his career choice as an actor, and he said he'd probably be doing the same things he's doing now even if he wasn't starring in major motion pictures - with one major difference.

"I might just sleep a little bit more," he joked.
