The highly-anticipated film based on Walter Isaacson’s Steve Jobs biography has already experienced its fair share of difficulties, with a number of award-winning actors being cast for the lead role and then dropping out days after their casting was announced. Disagreements regarding the production schedule have now reportedly created an even larger road block for the film, as they reportedly have caused Sony Pictures to sell the project to Universal Pictures.

Sony Corp. first acquired the rights to create a film based on Isaacson’s acclaimed Steve Jobs biography soon after the Apple Inc. co-founder’s death in 2011. The script for the film is being co-written by Aaron Sorkin, who won an Oscar for his screenplay for The Social Network, but the film has seen a number of surprising changes in its cast and production team lineup in recent months.

The Social Network director David Fincher was associated with the project soon after it was announced, but the biopic is now reportedly being helmed by Danny Boyle, director of the Oscar-winning Slumdog Millionaire. Leonardo DiCaprio was first cast as Jobs, but he soon dropped out and was replaced by Christian Bale, whom Sorkin claimed was “the best actor on the board in a certain age range.” However, sources told the Hollywood Reported that, after carefully considering the role and script, Bale officially turned down the project because he didn’t feel like he was a fit to portray Jobs.

Sorkin’s difficulty in finding an actor fit to portray his film’s lead character is likely the result of the demanding nature of the role.

“He has more words to say in this movie than most people have in three movies combined,” said Sorkin. “There isn’t a scene or a frame that he’s not in. So it’s an extremely difficult part.”

While Deadline has stated that Michael Fassbender is in talks over taking on the role, the film received another difficulty to overcome recently when its producers tried to press ahead on a faster schedule than Sony was willing or able to accommodate. Sources say that this caused Sony to drop the project, which was in pre-production, and sell it to Universal Pictures.
