Collecting celebrity guest stars like so many Portland residents collect scrap lumber for their "projects," IFC's Portlandia has announced a huge roster of famous faces due to visit the satirical Pacific Northwest in its third season. In addition to appearances from returning players Kyle MacLachlan, Jeff Goldblum, and Kumail Nanjiani, plus the addition of Chloë Sevigny as Fred and Carrie's new roommate, Roseanne Barr, Juliette Lewis, Rose Byrne, George Wendt, Bill Hader, Bobby Moynihan, Jim Gaffigan, Matt Berry, Matt Lucas, Dinosaur Jr.'s J Mascis, members of Dirty Projectors, and even tennis champ Martina Navratilova will all be stopping by as various people, many of them quirky. Also added: Patton Oswalt, who is quickly becoming the Samuel L. Jackson of cable television shows. Oswalt will be playing the entrepreneur behind a food truck that only serves biscuit-stuffed biscuits. Not really, but someone should play that.
