Justin Long will play Steve Jobs in iSteve
The parody will be available from the website Funny or Die. The picture will run 60 to 75 minutes and writer Ryan Perez said the script was written in three days and the movie shot in five days. Perez says that, "in true Internet fashion, it's not based on very thorough research -- essentially a cursory look at the Steve Jobs Wikipedia page. It's very silly. But it looks at his whole life."
Besides Jobs, there is also the Aaron Sorkin movie of Steve Jobs' life that will be based on Walter Isaacson's biography. That movie has yet to be cast.
