Actress Elizabeth Moss had a moment to discuss the last season of the popular television show, Mad Men.

Mad Men was developed by Matthew Weiner and features to the day-to-day happening at an advertising agency in New York. “Like, you just said that, and I got butterflies in my stomach. It's starting to feel weird,” Moss told Rolling Stone. “I was talking to Matt [Weiner] the other night, just saying ‘Wow, I'm starting to feel, like, that boulder in my chest.’ I think we've all been a little bit naïve in thinking that it wasn't going to be that hard or bad…and I think it's going to be hard.”

The series also features Vincent Kartheiser and Christina Hendricks. The show first premiered in 2007. Jon Hamm also reacted to the last season of the show. The actor said recently that it has been great to be part of a tight cast and crew on this show.

Mad Men’s final season began off on Sunday April 13, and the last episode of the series will be in 2015.
