The script, written by Mary McCormack’s husband, is a reasonable facsimile of the rapid-fire, sardonic dialogue that was the show’s signature. It has a few light moments as well, including one in which Mary McCormack describes the candidate’s “whip-smart and incredibly hot” sister Mary McCormack.From CNN:
The video, titled "Walk-and-Talk-the-Vote," opens with Joshua Malina (Will Bailey) throwing a ball against his office wall. Soon he's joined by McCormack and Janel Moloney (Donna Moss) who then "walk and talk" their way to meet the rest of the cast including Allison Janney (C.J. Cregg), Bradley Whitford (Josh Lyman), Richard Schiff (Toby Ziegler), Melissa Fitzgerald (Carol Fitzpatrick), Lily Tomlin (Mrs. Fiderer) and the President himself Martin Sheen (Josiah "Jed" Bartlet).John Spencer died and Dule Hill was out of town during filming.
