Elisabeth Moss says this memorable 'Mad Man' scene was not fun to shoot

But at an appearance on "Late Night with Seth Meyers" Thursday night, Elisabeth Moss, who played Olson, said shooting this now famous scene was not fun to do.

"It was not cool at all," she told Meyers.

"I was holding this box, and everything on 'Mad Men' is super real so they made the box really heavy. I was like, 'I can act that,' but no."

AMC/"Mad Men""And the cigarette is actually really difficult to do. James Dean makes it look super cool and easy but it's actually really hard to hold a cigarette in your mouth and walk."

AMC/"Mad Men""So I was trying to look cool, trying to not drop the painting, trying to not bump into the walls."

But there was something fun Moss got out of the experience. She chose the on-set music to walk to.

"I was like 'Stayin' Alive,' obviously," she told Meyers, referring to the Bee Gees song. "I'm walking down a hallway, what else would I be listening to?"
