There were not very many people who knew that Linda Cardellini was going to be appearing in Mad Men so, when she appeared as Sylvia in the Mad Men season six premiere, there were a lot of pleasantly surprised people. Linda has now admitted that she loved keeping her role in Mad Men a secret, especially from her friends and family.
Cardellini told Entertainment Weekly, "It's really fun [to keep a secret]! Usually people know what you're doing, especially with the internet. People know what you're doing sometimes even before you know. To have it be a surprise for my friends and family who haven't seen me do anything for a while because I've been home with my daughter, it'll be a really fun surprise."
Linda also went on to explain that there are always some things in the show, that even the cast are kept in the dark about, "Matt never gives it away! The secretive part isn't only for the audience. It's for everybody around set. I think it keeps everybody on their toes and guessing and it keeps everybody involved in the future of the show."
Linda Cardellini's character Sylvia is a friend of Don Draper and Megan Draper in Mad Men. We will get to see more from her and her latest character in Mad Men season six, which airs on AMC in the US and Sky Atlantic in the UK.
