A Steve Jobs biopic, simply titled Jobs, is already shooting, but it’s still adding to its cast, as THR reports that Matthew Modine has joined the movie, playing John Sculley, who Jobs recruited to lead Apple in 1983 and famously ‘fired’ the co-founder of the company two years later. Sculley remained as Apple CEO from 1983 to 1993.

Modine comments, “It’s my feeling – and I think there’s a lot of people who feel – that had John Sculley not fired Steve Jobs from Apple Computers and [let] Steve go on the journey that he did when he was away from Apple Computers, that we wouldn’t be speaking about Steve Jobs today.”

Ashton Kutcher is playing Jobs himself, with the film tracing the man’s story from the 1970s through to the 21st Century. Joshua Michael Stern (Swing Vote) directs, with Josh Gad starring as Apple co-founder Steve Wozniak. It’s due out this autumn, rushing into cinemas to get a good head start on a rival, slightly more official Jobs film, which is based on the acclaimed biography by Walter Isaacson and with a screenplay by The Social Network Oscar winner Aaron Sorkin.
