Schiff complained that his character is being "phased out" after a few episodes this season partly because studio owner Time Warner is a "corporate shadow (that's) constantly suppressing and regulating and watching over" the political drama and especially Schiff's role as communications director Toby, "who is somewhat conscience-driven and dynamic in his opinions. There is pressure to relieve him of his voice."

After the session, I found myself in follow-up chats with "The West Wing's" Richard Schiff and then "American Dreams" writer-producer Jonathan Prince. Plenty of material for a future column or columns. As the conversations went on, the lights were being turned out in the meeting room and pieces of the set were being taken down around us. It was real don't-let-the-door-hit-you kind of moment.

Richard Schiff, who plays liberal White House staffer Toby Ziegler on "The West Wing," said his character will be phased out this season by what he described as mutual consent. But then he tried to blame his departure on the corporate culture at Warner Bros., which produces the series."There is pressure to relieve him of his voice," Schiff said. Later he backtracked, saying it was not direct corporate control but that the studio had an influence on the show's budget. Yes, the studio does, and that's why it's called show business. "We're in a bottom line culture right now," Schiff said. "More money can be made if it's quicker, faster. In the days of Aaron Sorkin, it was quite expensive because his artistic process demanded more time. That has been eliminated."
After the press conference, Schiff continued to back away from his initial tone.
"I'm not accusing Warner Bros. of suppressing Toby in any way, shape or form," Schiff said. "It's not some suit at Warner Bros. that goes, 'That Toby, we've got to suppress him.' I know it sounded like that, but it's not what I mean, and that's stupid."
Basically, Schiff's frustration boils down to an artist who said his suggestions for his character were more often heeded under original show runner Sorkin than current show runner John Wells.

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."
