Given 'Mad Men's' notoriously secretive promotional campaign, as well as the recent inspiring yet cryptic 'Mad Men' season 6 poster, we wouldn't expect series creator Matthew Weiner to give up too many secrets as we head toward the April 7 premiere. Still, even Weiner can't prevent a look or two behind the curtain, as a new production featurette teases the dual idenities of Don Draper to come, as well as the "upheaval" in the show's future. Get a new look at the future of 'Mad Men' inside!

Social upheaval and change are the name of the game for 'Mad Men' season 6, according to the latest behind-the-scenes production video from AMC. The notoriously tight-lipped cast and crew couldn't show off any new footage of course (unless you count Harry Crane's new look), but did reveal the new season premiering April 7 would be "a real journey into learning about Don."

Rather cryptically (perhaps euphemistically?), series star Jessica Pare teases, "It's not what you think is coming. It's not coming in the way that you thought it was coming. It's probably not coming at all." Series creator Matthew Weiner more elegantly revealed that picking up in 1967 leaves very little room to ignore the social changing happening outside the walls of Sterling-Cooper-Draper-Pryce.
