Best known for: Peggy Olsen, Mad Men (AMC)
Weirdest role: "Voice" in Recycle Rex (1993)
Prior to her recent stint in the world of prestige drama, young Elisabeth Moss did a ton of voice work. While she lent her voice to some well-known shows like Animaniacs and Freakazoid!, she also worked on some lesser known cartoons. Case in point: Recycle Rex, a dopey promotional cartoon dinosaur in the style of Smokey the Bear, created by the California Department of Resources Recycling and Recovery. Though we imagine the world of Recycle Rex is fraught with less intrigue, adultery, and ennui than that of Mad Men, it is comforting to know that not only is Moss one of the best actresses around, but she gives a damn about the environment, too.
