"You're going to see opposition on the show, and you're going to see them making strong, compelling arguments. In our parallel West Wing universe, which is two years off from the actual universe, Bartlet's going to need to start running for re-election. And he's facing all kinds of opposition -- including, by the way, opposition to his left." - Aaron Sorkin

At this point in production, episode four is being filmed on the Warner Bros. lot. That requires creative scheduling to accommodate the days cast members will be in the Pittsburgh area filming."We've tried to put the trip over a weekend to be able to have some characters here only a day," Misiano said. "Hopefully [when you're watching episode four] you won't really feel like people have departed [to film these scenes in episode one]."

He is a fictitious U.S. president but Jed Bartlet from The West Wing may well teach Premier Bernard Landry a few tricks before the Quebec leaders' debate.Some members of Landry's entourage happen to be fans of the hit TV show and in particular an episode where Bartlet gets to practise his pithy one-liners for the leaders' debate.
They watched the show for ideas and will have Landry do the same sometime before the debate on Monday, March 31, between Liberal leader Jean Charest and Action d?mocratique du Quebec leader Mario Dumont.
"Yes, I plan to have him watch it," Landry's press aide Hubert Bolduc said yesterday. "I have the tape."
The episode, Debate Camp, features Bartlet and his key staff preparing for the debate in a rustic North Carolina conference centre. Senior staff play the various roles including star Sam Seaborn, who gets the job of being Robert Ritchie, the Republican Party candidate.
