They've finally staffed up at Princeton-Plainsboro. Fox has officially announced the casting of not four but five newcomers to the fellowship race on the hit drama House. Olivia Wilde ( The Black Donnellys, Mischa's O.C. crush), Kal Penn ( Harold & Kumar Go to White Castle), Peter Jacobson ( The Starter Wife), Anne Dudek ( Big Day) and Edi Gathegi ( Lincoln Heights) are coming on board as candidates for the plum opportunity (assuming you define "plum" as "learning from Dr. Crankypants").

With the flurry of new faces arriving in the wake of Foreman's exit, Chase's firing and Cameron's resignation, who's a keeper and who's a goner? Teases Fox, "Any effects of this 'housecleaning' or the changes it may bring to House professionally or personally remain to be seen." Ya think?
