‘Mad Men’ cast forgotten lines with a view of hot Jon Hamm

No one on “Mad Men” got mad looking at Jon Hamm.

John Slattery – who played Roger Sterling on the iconic AMC series – revealed the cast of Hamm, 51, were often so mesmerized they forgot their lines.

“When Hamm walked into a room in that getup, people would just go catatonic,” Slattery, 60, told the Independent of Hamm, who played ad exec Don Draper.

“Guest stars would sometimes approach him and their lines would go right out of their heads,” he said.

Slattery joked that “it happened more than once” because “they just didn’t know what to do.”

But Hamm wasn’t the only star on the show to gaga other actors, according to Slattery.

“[Christina Hendricks] walked into the room and people lined up — it was amazing,” he recalled.

Mad Men premiered in 2007 and ended in 2015 after seven award-winning seasons. The Emmy-winning drama chronicled advertising agency Sterling Cooper’s exploration of the changing times and conflicts of the 1960s.

While it’s hard to imagine Draper being played by anyone else, Slattery also confessed that he was ready for the role when the series first aired in the late 2000s.

“[Hamm] claims it made me in a bad mood the entire time we were filming the first episode, but I don’t think that’s true,” the Boston native explained. “At one point I saw him and I was like, ‘Oh — they definitely have this guy.'”

Hamm appeared on SiriusXM’s “Pop Culture Spotlight with Jessica Shaw” in September and discussed trying to distance himself from his role as Draper.

The actor said he landed a cameo in Kristen Wiig’s 2011 all-female comedy Bridesmaids, in which he played the jerk Ted, who only wanted to be friends with Wiig’s character Annie Walker for benefits.

“I made this film before there was a part, before there was a script, I said ‘yes’ to it. and [my] Agents said, ‘Oh, well, s–t. How can we, you know, ask for money?’ And I said, ‘Don’t worry. Just let me let go and have fun with friends,'” Hamm said.

He then pointed out that he couldn’t turn Wiig down after they developed a friendship during his Saturday Night Live hosting gig in 2010.

“We were in a couple of skits together and we hit it off like a house on fire, and she said, ‘Would you like to be in my movie, please? Please be in my movie.’ You know, no one knew it was going to be the global hit it was,” Hamm said. “But I knew it was going to be fun. And especially with this cast, I was like, ‘Sure, of course. Are you kidding me? Thank you for your concern. Of course I will.’”

“Mostly I drive [my agents] crazy because I say yes to everything you know?” he added. “I’m always showing up for people’s podcasts or whatever. But I like doing that.”
