WHITFORD JOINS STRIP CLUB: As teased weeks ago in Ask Ausiello, The West Wing’s Bradley Whitford has been added to the cast of Wing creator Aaron Sorkin’s NBC drama pilot, Studio 60 on the Sunset Strip. Whitford will play a producer-director and recovering cocaine addict on the series’ SNL-style sketch show-within-a-show. Also joining Studio 60 are Wing’s Timothy Busfield (playing a control-room director) and Sarah Paulson (as a Christian fundamentalist.)
