Colin Firth is set to team up with Michael; Fassbender for new movie Genius.
The movie is a big screen adaptation of Scott Berg's Max Perkis: Editor of Genius and will see Michael Grandage in the director's chair.
The script has been penned by John Logan, who has just penned Skyfall and Hugo, and work on the movie is set to get underway in 2014.
Genius centres on the real-life relationship between literary giant Thomas Wolfe (Fassbender) and renowned editor Max Perkins (Firth).
Wolfe and Perkins develop a tender, complex friendship. Transformative and irrepressible, this friendship will change the lives of these brilliant, but very different men forever.

He is also completed work on Devil's Knot and The Railway Man - he is also expected to reprise the role of Mark Darcy when a third Bridget Jones movie goes ahead.
