Critic’s Pick: ‘The Man in the Machine’ a full portrait of Steve Jobs

With director Danny Boyle’s “Steve Jobs,” starring Michael Fassbender, coming up later this fall, it might be a good idea to catch this new documentary and get up to speed on the man behind Apple. Veteran documentarian Alex Gibney (“Taxi to the Dark Side,” “Enron: The Smartest Guys in the Room”) uses his trademark mixture of talking heads, archival footage and investigative zeal to provide an engrossing, at times unflattering, look at one of technology’s most influential figures. Gibney’s “Steve Jobs: The Man in the Machine” is at its best providing a brisk summation of the man’s life. Or lives, for Jobs seemed to have been more people than one would have thought possible.
