"Jobs" based on the life of Apple co-founder Steve Jobs and Kutcher, 35, is playing the titular character in the film, which will hit theatres an August 16.
"He (Steve) cared more than anyone else - with every fiber of his being - about the quality of that experience. He dedicated his entire life to building the greatest personal electronic devices in the world and I think, to date, he's done it," Kutcher said in a statement.
The movie explores Jobs' life from the keenness and self-discovery of his youth to his rise as a veritable icon who changed technology.
"I'm just soldering it together and I don't know what the hell I'm doing or how this stuff works. And Ashton just started talking about it. He had studied everything. He not only knew everything about Steve, and about Apple- he knew how the circuitry worked," Haas said.
