Arguably the greatest episode of "The West Wing," the Season 2 finale "Two Cathedrals," is about how one of TV's best presidents responds to a cruel act of God. Kathryn Joosten played Dolores Landingham, the personal secretary to Martin Sheen's President Jed Bartlet, for the first two seasons of the hit NBC political drama. A fan-favorite character, Mrs. Landingham dies unexpectedly when she's hit by a drunk driver at the end of the sophomore season's penultimate episode. Joosten unwittingly sealed Mrs. Landingham's demise at an event when she stepped out to smoke a cigarette next to "West Wing" creator Aaron Sorkin. She casually mentioned that she was auditioning for roles on other shows and might have to quit "The West Wing" if she got a regular part.
