#80 - TV Episode of the Day: The West Wing Season 2, Episode 18: SEVENTEEN PEOPLE. Teleplay: Aaron Sorkin
An episode so strong there is an entire website about it: http://seventeenpeople.com/
Called a “BOTTLE” episode. Is produced cheaply and restricted in scope to use as few non-regular cast members, effects, and sets as possible. Occurs when the show is over-budget and they need to shoot a cost saving episode.
