I still want Ed Harris.
I like Bale, but Harris has the depth required. If you've seen him in Pollock, you know he's the one to play a complex character like Steve Jobs.
Bale is the "Hollywood choice" to bring in the Batman audience, but nobody becomes a character like Harris. Maybe Depp if you think Harris is too old and Depp still has the fire to prove himself.
I just hope fans aren't expecting too much from Sorkin. The Social Network had the merest acquaintance with the facts of that tale, and the Isaacson biography is not noted for its grasp of the technological. Witty Sorkin may be, but Sorkin is unlikely to 'get' the facts or the technology. What Sorkin does best is politics, and Steve Jobs was the very antithesis of politics.
