The first Season 4 video exclusive for iPhone users is here: Production designer Dan Bishop and set decorator Claudette Didul talk about how they moved Mad Men squarely into the '60s with individually personalized, intentionally smaller offices. While most everyone else gets squeezed into the cramped space "like a puzzle," it's still no surprise that Don gets the big corner office with a 7-foot-long desk!

Power up your iPhone for a behind-the-scenes look inside Sterling Cooper Draper Pryce's new offices.
