Since Apple founder Steve Jobs died in 2011, there have been two films about his life. First was 2011's Jobs, starring Ashton Kutcher, which flopped with the critics and at the box office. And now Danny Boyle and Aaron Sorkin are taking a stab at it with the festival hit starring Michael Fassbender. It's titled, cleverly, Steve Jobs.

After Christian Bale had to drop out of the role, Fassbender was surprised to be offered the part. "I got approached by Danny Boyle," he says. "He sent me the script and asked me if I was interested. I read the script and it's amazing writing - amazing - and Danny's a phenomenal director, and just a wonderful person. So I jumped on board. It's really that simple."

He laughs off comments that he isn't physically right for the role. "Obviously I don't look anything like Steve Jobs," he laughs. "That was the first thing I said to Danny! So we decided that we weren't going to try to make me look anything like him. We just wanted to try to encapsulate the spirit and make our own thing of it."

To understand the character, he met a number of people who knew Jobs well. "The one thing that stuck with me was how much of an impression he made on these people," he says. "Obviously when he was alive, but since he passed away, you could see that he was still very much present in their lives. Even if the relationships were difficult, there was a sadness and a love there for him that I felt was pretty clear."

But Fassbender openly admits that there was one side of the man he would never get to grips with. "I'm not very interested in technology," he says. "I use it pretty poorly, and it behaves strangely around me. Things crash all the time. I rejected the mobile phone for so long, until people were like, 'We can't get in touch with you. This can't go on.'"
