In a talk after the premiere of the Steve Jobs biopic 'jOBS,' Ashton Kutcher said that he suffered a health scare in preparing for the title role as a result of adopting the late Apple cofounder's fruit-only diet.
According to Kutcher, the all-fruit diet lead to pancreatic problems so serious that he was prompted to visit a local hospital for treatment, reports USA Today.
"First of all, the fruitarian diet can lead to like severe issues," Kutcher explained. "I went to the hospital like two days before we started shooting the movie. I was like doubled over in pain."
Those who have seen the film's first screening said it suggests Jobs was a proponent of the diet.
"My pancreas levels were completely out of whack. It was really terrifying ... considering everything," Kutcher added, alluding to the pancreatic cancer that ultimately took Jobs' life on Oct. 5, 2011.
Other than taking on Jobs' diet, Kutcher prepared for the role by studying hours of Steve Jobs footage to replicate the tech guru's mannerisms, including a hunched-over walk and unique speech cadence.
Directed by Joshua Michael Stern, jOBS takes place over the defining 30 years of Jobs' life, including pivotal moments in Apple history such as the launch of the first Mac and the iPod.
The film has garnered mixed reviews with critics, but Apple cofounder Steve Wozniak went on record as being somewhat critical of the characters' authenticity.
After having a well-received premiere at the 2013 Sundance Film Festival, jOBS is schedule to open nationwide on April 19.
