There's certainly been a lot of activity lately coming out of Danny Boyle's Steve Jobs. Last week there was the big news that Sony had put the film into turnaround. Then news broke that Universal had picked up the picture. Now there's word that Natalie Portman is in talks to join the Aaron Sorkin-penned feature.If everything pans out, Portman would be joining Seth Rogen and, depending on who you ask, Michael Fassbender.
