PASADENA, Calif. -- As AMC's "Mad Men" readies a new season, questions raised at the end of last season swirl: Will 1960s era ad man Don Draper (Jon Hamm) be faithful to wife Betty (January Jones) now that she's pregnant? How will the declaration by junior copywriter Peggy Olson (Elisabeth Moss) to peevish Pete (Vincent Kartheiser) that she had his baby and gave it up for adoption affect their working relationship?

You won't get answers to those questions from series creator/executive producer Matthew Weiner who is notoriously nervous about giving away too much information, even a detail as trivial as what year the series has advanced to when its third season premieres at 10 p.m. Aug. 16.

"I try to have a theme when I start [a season] and it becomes more complicated as you go," Weiner said in a staging area for an AMC cocktail party that, like a scene on "Mad Men," was thick with actors' cigarette smoke. "[This season] started with dealing with change. It's a cliche that people face change in their lives but there is a reaction that people have. Some people are thrilled by it and some people are terrified by it."

Jones said Betty and Don begin the new season less at odds with one another than they were last year.

"That last episode where they held hands and she said, 'I'm having a baby,' I think it's been a rebirth for them," she said. "They're being very nice to each other and they're looking at this baby as a new beginning for them. The pregnancy is a very optimistic time for them."

But with change in the wind, that may not last.

"That's not just talking about the characters and stories, it's about the culture as well," Hamm said of societal shifts that will be felt by the "Mad Men" characters. "We're moving forward in time and the country is very much changing and people change along with it. I think we've seen that in the last 2-3 years in this country."

Hamm said his character's California sojourn last season taught Don he has "to take advantage of the now and [it makes him ask], what does he have right now? What's important to his life right now?

"I think at a very fundamental level, Don is a survivor and an adaptor," Hamm continued. "When he senses the mood of the room or the street or anything shift, he's very attuned to that. He's not necessarily on the cutting edge or the leader of those changes, but he is an adaptor."

But what about Don and Betty?

"Is Don going to be more faithful?" Hamm says, repeating a question he's been asked. "Well, people change and people stay the same. I'll leave you with that."

At least viewers can count on ad man Ken Cosgrove (2004 Carnegie Mellon University graduate Aaron Staton) to be content.

"This is a world where people are looking for happiness and Ken seems to be someone who has found it or isn't desperately searching for it," Staton said. "He's content on a day-to-day level and I think that's much to the chagrin of his peers. You saw when he had the story published in the first season and I think there's a certain jealousy and even resentment that he doesn't have that same air of desperation, of concern."

For Kartheiser, playing a character who occasionally rants like a sullen child has its challenges, but he trusts the show's producers to strike the right balance in editing. He'll offer varying degrees of Pete's petulance in multiple takes for a scene.

"My job is to give choices and I try to interpret Matthew's work with all its subtextual brilliance, which is probably one of the hardest parts of my job," he said. "We have an amazing crew of people who know how to form a story every week and I'm just a very small color on that palette."

But it's a color that evokes a strong reaction. Kartheiser said he met a restaurant hostess who told him she throws shoes at her TV whenever his character appears.

"I was trying to get a table and she was like, 'You're not Jon Hamm,' " Kartheiser recalled. "She was joking."

Despite comparatively low ratings, "Mad Men" has certainly entered the zeitgeist -- it's been parodied on "The Simpsons" and "Saturday Night Live." Hamm, who hosted "SNL" this past season, has a pencil drawing from the "Simpsons" spoof framed and hanging on a wall in his home.

For Jones, the show's success means she can't go to vintage stores and buy '50s and '60s clothes anymore. But she's evidently free to expand her diet.

"If anything, they want us to gain weight because they want a soft, voluptuous woman," she said. "I got told a couple days ago I looked too skinny and I was in trouble."

A reminder to Comcast subscribers in the City of Pittsburgh: On Monday the cable company will move AMC from its standard cable tier to digital starter. The channel number will remain the same.

At 5 a.m. Monday WTAE will drop its weather/traffic digital subchannel (Channel 4.2) in favor of This-TV Pittsburgh, a free movie channel of films from the MGM, United Artists and Orion vaults. Hearst Television, WTAE's owner, signed an affiliation agreement to carry This-TV on its stations' digital subchannels earlier this year.

Anecdotally, I've heard more viewers express an interest in and appreciation for WPXI's RTN channel than any other digital subchannel, so This-TV Pittsburgh seems like a better bet for WTAE than the weather channel it replaces.

In addition to over-the-air, This-TV Pittsburgh can be found on local cable systems, including: Comcast (Channel 204), former Adelphia Comcast (Channel 188), FiOS TV (Channel 461), Armstrong (Channel 450) and Atlantic Broadband (Channel 110).

Next week Philadelphia Inquirer television critic Jonathan Storm and I will answer TV questions in two online chats.
