Alongside her work on Community, Alison Brie is best known for being the woman who inexplicably married - and stayed that way - Pete Campbell on Mad Men, Trudy. Pete, faithful and loving husband that he is, keeps a picture of his darling wife on his desk at work. However, back in the pilot episode, the person in the frame is not Alison Brie. Pilots are obviously filmed before a cast is fully locked-in, so its likely that Trudy simply hadnt been cast at this point. It does offer a glimpse of a world where Alison Brie isnt on Mad Men though, and that is a world that no one wants to live in. So who is the mystery woman portraying Petes wife? None other than Matthew Weiners mother.
