Can't wait for "Mad Men" to finally return? Neither can I -- it has been 459 days since we last saw Don Draper and the Sterling Cooper Draper Pryce gang in "Tomorrowland," and so many questions linger going into Season 5's big two-hour premiere (Sunday, March 25, if you don't already have it circled on your calendar).
HuffPost caught up with the cast -- including Jon Hamm, Elisabeth Moss, Christina Hendricks, John Slattery, January Jones and creator Matthew Weiner -- who were all as tight-lipped as ever about what to expect next season. They would only non-jokingly joke that they'll get fired if they say anything. (They will.)
The "Mad Men" cast did, however, have some things to say about the new season. "I think this season is the best yet. I really do," Slattery said. "We were all commenting that it felt like the first season. 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. It's somehow simpler."
Do his castmates agree? "This season I think is our best season, script-wise. 100 percent," said Rich Sommer, who plays Harry Crane. "I really can't imagine how anyone would be disappointed, and I think that it definitely rewards those people who have been there from the beginning. It's not a show you can start from the middle ... well, you can, but you'll not only miss information, you'll miss nuance. There are literally glances that happen between two characters where it's like, 'Oh shit!'"
"A lot happens this season!," Hendricks agreed. "A lot of last season, we were wondering what was happening with Don Draper, what was happening with his marriage. But every character experiences so much this year. It's very exciting."
"I heard something that Matt [Weiner] said tonight," Moss said, "which is that this season is about every man for himself. I just thought that was so interesting ... I'd never heard him say it before, but I think that is the most perfect way of describing this season. And I think that's the parallel to Season 1 as well."
Speaking of Season 1 -- and all the previous seasons -- the castmates had to answer an even tougher question: What's your favorite "Mad Men" episode ever?
