Ashton Kutcher recently admitted that preparing to play Steve Jobs in the new "jOBS" film landed him in the hospital.
The biopic about the Apple founder and tech innovator premiered at the Sundance Film Festival on Friday, January 25. The actor told reporters that following Jobs' fruitarian diet lead Kutcher to develop health issues.
"I ended up in the hospital two days before we started shooting the movie," Kutcher said, according to The Associated Press. "I was like doubled over in pain, and my pancreas levels were completely out of whack, which was completely terrifying, considering everything."
Jobs died of complications from pancreatic cancer at age 56 in October 2011. Kutcher was one of the first celebrities to react to the news of Jobs' death, writing on Twitter on October 5, "Today we lost a Giant who will be missed even by those who didn't know him. We have all surfed on the wake of Steve Jobs ship. Now we must learn to sail, but we will never forget our skipper."
The "Two and A Half Men" actor stars as Jobs in the film which chronicles 30 defining years in the tech innovator and entrepreneur's life. "jOBS" is described by the Sundance Film Festival as "a candid, inspiring and personal portrait of the one who saw things differently."
Kutcher's casting as Jobs was announced in April and the film also stars Dermot Mulroney, Josh Gad -- who plays Apple co-founder Steve Wozniak, Lukas Haas, J.K. Simmons and Matthew Modine. The movie was directed by Joshua Michael Stern, who wrote and directed the movie "Swing Vote."
The 34-year-old actor said playing Jobs "was honestly one of the most terrifying things I've ever tried to do in my life."
"It was kind of like throwing myself into this gauntlet of, I know, massive amounts of criticism because somebody's going to go 'well, it wasn't exactly...,'" Kutcher later said, according to the wire service.
Kutcher reportedly prepared for the role by watching hundreds of hours of footage, listening to Jobs' old speeches and interviewing Jobs' friends.
"I admire this man so much and what he's done. I admire the way he built things," Kutcher said of Jobs. "This guy created a tool that we use every day in our life, and he believed in it when nobody else did."
"jOBS" is not the only biopic about the Apple innovator in the works. There's also a film about Jobs being written by Aaron Sorkin, according to The Daily Beast. Sorkin told the outlet of his film in November, "This entire movie is going to be three scenes, and three scenes only, that all take place in real time."
