Downton Abbey's fourth season had a blockbuster premiere this past weekend. We revisit a conversation with Lesley Nicol, the show's feisty but devoted head cook on PBS's megahit. She tells us how she landed the plum role and talks about a one-woman play she brought to Chicago.

View behind-the-scenes photos, and watch a web-exclusive conversation with Nicol as she talks about the wide-ranging audience of Downton Abbey, and gives us her thoughts on the Mrs. Patmore doll.
