Giles Matthey has few credits to his name, his IMDB page has just three listings, a movie called Hunter that is in post-production, and the TV shows True Blood and The Good Wife.
Casting a relative unknown as the famously reserved British designer may be a shrewd move, however, as it plays to Jony's air of mysteriousness.
More casting details have also been announced:
Kevin Dunn (Transformers) will play the roll of former CEO Gil Amelio (') and J.K. Simmons (Law & Order) as early Apple investor Arthur Rock.
Smaller roles include Elden Henson (The Butterfly Effect) who plays early development team member Andy Hertzfeld (responsible for larger portions of the Macintosh system software and, more recently Google Circles); and Lenny Jacobson as Burrell Smith, plus Victor Rasuk as Bill Fernandez (Apples first official employee).
