'Mad Men' Season 5 Promo: Roger Is Back (VIDEO)

It's been a long time coming, but the "Mad Men" Season 5 premiere is finally upon us -- and so are the new promos. Get a sneak peek at the new season above.

The AMC drama returns with a two-hour premiere on Sun., March 25 at 9 p.m. EST and the cast is starting to drop hints about the long-awaited return.

We've somehow circled back after all the details and all the plot development that's happened with everybody ... it's kind of circled back to the sort of tunnel vision on each character and various elements of each character that they've dialed in on.

In the new promo above, check out Slattery's Roger back in action: the debauchery, the swagger, the highballs, the vests -- it's all back.
