Is Megan doomed on Mad Men? Certainly, her marriage to Don seems to be on the rocks, but there are also those persistent rumors that Megan could be murdered, à la Sharon Tate — a theory strengthened by many could-be clues in last Sunday's season premiere. When Vulture caught up with Jon Hamm last night at the Public Theater’s opening night fête for The Library — he was positively beaming when his longtime girlfriend Jennifer Westfeldt, who stars for director Steven Soderbergh in the play, emerged at the after-party — we asked for his take on the Megan-is–Sharon Tate line of thinking. "I don’t give very much credence to it," said Hamm. "Although, certainly it was on people’s minds in the world of the show. It’s an interesting theory, but I don’t know how much validity there is to it. But it’s a great compliment that people are thinking that deeply about the show."
As for Don's strangers-on-a-plane dalliance with an alluring widow played by Neve Campbell, Hamm told us that he only learned of her casting on the day of shooting; fortunately, the two had chemistry to spare. "It turned out great, and I thought the scene was surprisingly intimate and fascinating," he said. "I had a blast working with her. She’s a lovely gal." Ultimately, Don turns down her advances — does that mean there's still hope for him, after so many seasons of philandering and self-abuse? “I think I’m uniquely rooting for him,” Hamm said with a chuckle. "It’s been a long, downward spiral. I’m hoping for peace and resolution and balance and all of those things in his life."
