Jon Hamm lays all his cards on the table for Vanity Fair contributing editor Jim Windolf. Find out how he feels about playing Don Draper and what it was like working in adult film!

"This is the best job I've ever had and maybe ever will have in my life-it's so fun to play all of this," Hamm explains of his role on the award-winning series. "It can be relentlessly dark. It can be terribly sexually inappropriate, is a way to say it. But who else gets a chance to do any of that stuff? There's so much there."

The show's creator Matthew Weiner praises Hamm and explains his vital imput on the series.

"He's the first, outside the writers' room," Weiner said, adding Hamm knows how it will end. "I try stuff out on him. When we get stuck in the writers' room, I go down there and have a conversation with him."

When asked if they ever disagree, Weiner replied, "The relationship would be bullshit if we didn't have disagreements."

A recently resurfaced clip of 1996s "The Big Date", which Hamm remembers as a dark point in his life.

"I was actually at that time working as a set dresser for Cinemax soft-core-porn movies," he tells the mag. "It was soul-crushing."

Hamm's love for the industry came at an early age, when his father would take him to parties and he would watch TV.

"Eleven-thirty would roll around-10:30 in the Midwest-and the big huge 22-inch TV would be tuned to "Saturday Night Live." I would sit two feet in front of the TV and stare and watch the whole thing." 

He even took the young star to the Animal House.

"[and] I was like, 'Whoa!' I think I was seven. This was before my mom was dead. So it was a curious decision."
