Apple's late co-founder Steve Jobs is to be portrayed by Ashton Kutcher in an upcoming biopic, and in interviews this week, the actor has confessed that he was "terrified" about playing Jobs in the movie.

During an interview published by The Verge this week, Kutcher admitted that taking on the role of Steve Jobs in the new film, which is set to hit cinemas in August, was a scary prospect. "It terrified me, and most of the great things I've been able to accomplish in my life were things that terrified me," he said.

"I almost felt compelled to defensively play the role," Kutcher continued. "I wanted to make sure it was protected. Even if I screw it up and totally bomb it, I love that guy. I love that guy. I'd rather have someone that cared about him screw it up than someone who didn't. "

In a separate interview on The Tonight Show this week, Kutcher also revealed that he had passed up an opportunity to meet Jobs before he died because he had to work that day.

"I had an opportunity to meet him about six months before he passed away. I was working that day and I couldn't go," Kutcher explained. "In hindsight, I had the opportunity to meet the Leonardo da Vinci of our generation and I missed it. That really affected my decision to take on the role."

"I'll never forget the moment I heard that he died. And I pulled my car to the side of the road and kind of took a moment. I got home and I realises, I sat down on my computer and started doing some work and I realised all the relationships I have in my life are held together by the glue that he laid down.

"And all the work that I do, in whatever capacity that I do it, and all the entertainment I consume… here I have my Apple computer and my iPhone… all these things, and I realised that I had taken him for granted, and taken for granted the contributions he actually gave to society.

"I actually had a real emotional moment that day. I actually reached out to a couple of my friends. I do a lot of work in the tech venture space, and they had the same response. So when I got offered the role, I wanted to ensure that his legacy was told from someone who admired him."

Jobs is set to be released in cinemas in the US on 16 August, but a UK release date has yet to be announced. The film premiered at the Sundance Film Festival in January, but was met with mixed reviews. Apple co-founder Steve Wozniak, played by actor Josh Gad in the film, has blasted the movie.
