On October 9, Steve Jobs starring Michael Fassbender, directed by Danny Boyle, and written by Aaron Sorkin launched in limited release, with a wider rollout planned for Friday, October 23.

With more people starting to see the film out of the film circuits, and with even more theater patrons about to get their taste of Sorkin’s view on Apple’s co-founder, legendary technology reviewer Walt Mossberg has penned his thoughts on the film, on the Steve Jobs he knew, and how those two things are very, very different. With Mossberg’s look at the film and Jobs himself, we get to hear from someone who spent time with Jobs over the course of 14 years, and someone who doesn’t currently work for, and has never worked for, Apple.

While Steve Jobs has been getting a ton of praise across the board, from its acting, direction, and especially the writing, there are many that aren’t pleased with the film’s depiction of its title protagonist. There have been many think pieces about knowing the “real Steve Jobs,” and, mostly, how the upcoming biopic simply doesn’t depict that Jobs, instead favoring a heavily fictionalized version of the nonfiction individual, leaning more towards drama than reality.

Of course, it’s a film, and while the movie is based on an authorized biography written by Walter Isaacson, Sorkin obviously took some liberties in constructing his script. As Mossberg even points out, this isn’t the first time that something like this has happened with such a high-profile individual. In 1941 Orson Welles, a legendary director and writer for his time, put together a movie called Citizen Kane, which is based on an actual human being, the newspaper kingpin William Randolph Hearst. Welles, like current-day Sorkin, took liberties with the character depicting the real life individual, all for the sake of the story.

But unlike Hearst, Jobs can’t defend himself. So perhaps that’s why Mossberg has put together his thoughts on the film and the major differences.

Simply put, Mossberg says that the Steve Jobs depicted in the film isn’t the man he knew:

“Unlike Mr. Sorkin, I did know the real Steve Jobs, for about 14 years — the most productive and successful 14 years of his career. I spent scores of hours in private conversations with him over those years, and interviewed him numerous times onstage at a tech conference I co-produced. And the Steve Jobs portrayed in Sorkin’s film isn’t the man I knew.”

Mossberg points out that Sorkin decided to go the route he did so that he could “cherry-pick and exaggerate” only certain elements of Jobs from a time when he was young and immature. Indeed, the film does focus on Jobs’ daughter, and Jobs’ lack of acknowledgment that she is his daughter from an out-of-wedlock marriage. It’s a crux point for the film, as many have pointed out, but Mossberg says it doesn’t show the real Steve Jobs.

Moreover, the film doesn’t articulate that Jobs launched the iPhone, showcase the passion he had for launching products, his tendency to listen to colleagues, and how he ignored Wall Street over the years. That’s because the film doesn’t show Jobs actually running Apple as a company, but instead focuses on the personal interactions with Jobs and those closest to him at one stage of his life or another.

“Nobody basing their knowledge of Steve Jobs on this film would know that he had a happy marriage, that he loved his children, and that he led the creation of the iPhone. They wouldn’t have seen the passion of his actual product introductions, because the conceit of the film is that it takes place backstage just before three of them, and never shows the actual events. They would never have seen how he curated product design, took advice from colleagues, and steadfastly ignored Wall Street, because none of the movie shows him actually running Apple.”

Mossberg does point out that the movie simply gets some things wrong, too:

“The movie mangles too many facts to list here. Mr. Jobs’ intimates tell me he never held serious conversations with old collaborators and foes in the moments before he took the stage; he was intensely focused on his presentation. His early colleague, Joanna Hoffman, was long gone from Apple by the time Mr. Jobs returned to launch the iMac, contrary to what the movie says. And I knew former Apple CEO John Sculley, who is depicted as sort of a kind, sage figure in the film, but who, in my view and that of many others, wasn’t very sage in running Apple.”

The full editorial is certainly worth reading, especially in light of the film opening up nationwide in just two days. While film critics are raving about it, those in the tech industry that were closest to Steve Jobs continue to raise awareness that this is not an accurate depiction of the man, which is important.
