Premiering Thursday, Oct. 15 on the streaming service, A West Wing Special to Benefit When We All Vote marks the first time in 17 years that the original cast of the Emmy- and Peabody Award–winning drama series will come together, with creator Aaron Sorkin and executive producer/director Thomas Schlamme, for a theatrical stage presentation of the “Hartsfield’s Landing” episode from Season 3.
Rob Lowe, Dulé Hill, Allison Janney, Janel Moloney, Richard Schiff, Bradley Whitford and Martin Sheen all will reprise their respective roles from the episode.
