Although Linda Cardellini has became associated with Don Draper's (Jon Hamm) latest mistress Sylvia on "Mad Men" these days, the actress got her start playing Lindsay Weir on "Freaks And Geeks" from 1999-2000.
The series was short-lived -- it lasted only a season -- but it's responsible for launching the careers of actors like James Franco, Seth Rogen, Jason Segel and Busy Philipps. And according to Cardellini, they've all remained friends.
"Oh, we see each other. You constantly run into each other," Cardellini explained while on HuffPost Live. "Busy, I just gave her a baby shower. Sarah Hagan, I was just invited to her art show. It's a small world in this business.
"It was such an amazing time in all of our lives and careers," she added. "It's one of the most special things I've been a part of."
Catch Cardellini on "Mad Men," Sundays at 10 p.m. ET on AMC.
