Katherine Waterston to join Fassbender in Jobs biopic

Katherine Waterston has been cast as the female lead in the Steve Jobs biopic.

The eagerly awaited film has encountered numerous casting problems over the last few months - such as Christian Bale backing out of the project - but it finally appears to be coming together, with Waterston cast as Chrisann, Jobs' long-term girlfriend and the mother of his first child.

The 34-year-old actress, who has previously starred in 'Boardwalk Empire', 'Inherent Vice' and 'Robot & Frank', will appear on screen alongside Michael Fassbender, who has been cast as Jobs, Deadline reports.

The Danny Boyle-directed film will also feature Seth Rogen, who will play Steve Wozniak, the co-founder of Apple.

Earlier this month, leaked Sony emails revealed that scriptwriter Aaron Sorkin wanted Tom Cruise to play Steve Jobs in the new biopic.

He said: "This used to be an event. I don't know who Michael Fassbender is and the rest of the world isn't going to care. This is insane."

However, he subsequently backtracked, saying Michael is a suitable candidate for the part of Jobs, who died in October 2011, aged 56.

The film will start production in 2015.
