Neve Campbell appears on the season premiere of "Mad Men" in a guest-performance referred to as "a bit scary" during a recent interview.

The seventh and final season of AMC's hit show premiered on Sunday, April 13, opening with a scene between Campbell and Jon Hamm, who portrays Don Draper. The Campbell took on the guest-role of widow who takes a liking to Don after sitting beside him on a flight, but first, the actress was introduced to the regular cast of characters.

"I was really excited to be a part of it," the actress revealed to Entertainment Weekly. "I got there, and that was a bit scary going onto a set where everybody knows each other for so long. It's a bit like the first day of school. But everyone was really open and welcoming."

Campbell went on to explain her observation of the camaraderie among the "Mad Men" cast, which includes the aforementioned Hamm, January Jones, John Slattery, Christina Hendricks, and Elizabeth Moss, among many more.

"What I loved about the show is that they all really dig each other, and they're all really great friends," she told EW. "I was surprised, actually- outside the hair and makeup trailer, they've built a big porch with couches and food and tables. So everyone really gets along, they're friendly with each other, they enjoy themselves. They're all sad that this is the last season, you can see it. It's a chapter of their lives that's meant a lot to them and it seems like it's been a positive one for them, so it was a really nice vibe."

On working with Hamm, Campbell revealed that her scenes on "Mad Men" were captured within two days.

"We spent the afternoon shooting the scenes and getting to know each other and coming up with the energy between the characters," the actress told EW. "And [Hamm is] so talented and he knows his character so well, and is very very clear and so present in the character."

Despite the details on the cast, Campbell avoided any further questioning about her "Mad Men" character or if she will appear on any future episodes of the show. "Mad Men" airs Sundays on AMC at 10 p.m. EST.
