Mad Men's upcoming season is due for a big change, when season 3 part-timer, Jared Harris, becomes a regular character in season 4, which is due to start sometime in summer, 2010.
Jared Harris is Lane Pryce in the series, and up until now, he has come and gone throughout the show. During season 4, though, the newly built law firm is set to put Jared Harris's character up at the top in the list of main characters in the show.

He has a lot to live up to (three previous, flourishing seasons of the show), but he's earned it with the small yet important role he's played in Mad Men so far. We'll see how it goes, and I for one can't wait for the fourth season to start.
