In 2013, Kutcher played the man in the drama, "Jobs". Fassbender, 38, who plays the late Apple co-founder from his late 20s to his mid-40s, said he was aware he does not look like Jobs, reported Entertainment Weekly.
"Obviously, I don't look anything like Steve Jobs. That was the first thing I said to Danny. Christian Bale looks a lot more like Steve Jobs. (To prepare for the role) I studied Ashton Kutcher," he joked.
"Steve Jobs" stars Kate Winslet as ex-Macintosh marketing chief Joanna Hoffman, Seth Rogen, as Apple co-founder Steve Wozniak, Jeff Daniels as former Apple CEO John Sculley, along with Katherine Waterston, Michael Stuhlbarg.
The film will release on October 9.
