It looks like Don Draper and Peggy Olsen can work again.

The tough advertising execs from Sterling Cooper Draper Pryce will finally return in "Mad Men" on AMC March 25, putting the first episodes of the show on air since its fourth season finale in October 2010.

By the time it premieres, it will be 1 year, 5 months and 9 days since the last episode aired. Or if you really need your "Mad Men" fix, it will be 12,624 hours of life without "Mad Men."

The spring premiere will be the first for the show, which typically airs as part of AMC's summer schedule. The delay was a result of tense negotiations between AMC and showrunner Matthew Weiner that tried to reduce the length of episodes, and make other changes to the show.

The premiere will actually be almost a year from when AMC first announced there would be a fifth season, despite the fact that Weiner had not signed a new contract to return.

"I don't understand why, with all of the success of the show, they suddenly need to change it," Weiner told The New York Times last March while he was still negotiating a new deal. "All I want to do is continue to make my show, and make it in the way I want to, with the people I want to make it with."

Few details have been released about the show's fifth season, except that Jon Hamm, who plays Draper, will direct the first episode. It will be his first time as a director.

What cast will return and what won't is still a big question. Robert Morse, who plays senior partner Bert Cooper, is the biggest question mark. Cooper abruptly quit the firm late in Season 4, and his character was not seen after that. While other characters in the past have disappeared, it's unclear if that would be the same for Cooper, who has been seen as a primary supporting character on the show.

The fourth season of the show received the best ratings yet for "Mad Men." While less than a million people tuned into the series premiere of the show, the fourth season premiered July 25, 2010 with just under 3 million viewers.

Despite 17 months off, "Mad Men" will not miss a beat at the Emmys, where it has won Outstanding Drama four years in a row. The show has a chance to beat "Hill Street Blues," "L.A. Law" and "The West Wing" for the most Outstanding Drama wins by a single series this year, if it's nominated and wins.
