From the Daily Breeze:
"Lights, camera, action: Film crews were out at El Segundo High School again on Wednesday, giving the picturesque campus yet another cameo role.
This time it was for NBC's "The West Wing." Principal Jim Garza said the school served as a campaign stop for Democratic hopeful Matt Santos, who is played by actor Jimmy Smits.
According to Garza, crews shot the fictional candidate arriving in his motorcade and entering the school, surrounded by extras cast as supporters and members of the press corps. Then there were a few interior shots.
"It was pretty low key," he said. "They're nice people to work with."
