Vice President Mondale finishes making his point that the President has the right to take his case over the head of Congress directly to the American people.

Suddenly Senate Majority Leader Robert C. Byrd (W.Va.) is on screen staring straight ahead warning that a president could find such a practice "counter-productive."

A Sunday morning TV panel show? No, the Mondale-Byrd juxtaposition is one of many remarkable moments in a series of four films the United States Information Agency is making on the Carter administration for showing abroad.

Edward P. Morgan, who opens and closes each film with a commentary and conducts all the interviews, was given wide latitude to make the kind of rhetorically smooth observations that are a staple of television's analysts.

Morgan ends the first film giving both sides of the argument whether President Carter's bluejeans, banishment of limousines and other moves represent a victory of "work over trappings" or are symbols and little else.

He ends the second by observing signs of rough sailing ahead in relations between the White House and Congress.

Morgan's comments, as well as his questions during the interviews, make the films free of the made-by-the-government stamp one might expect.

By the same token, the films will not be easy going for any audiences but those quite familiar with the U.S. political scene.

Although the films will be made available for broadcast on television in English, French and Spanish to nations desiring to use the programs, USIA officials' primary goal is to reach sophisticated audiences through screenings arranged by public affairs officers abroad.

If the exchanges on such phenomena as impoundment, the War Powers Act, the Trilateral Commission and possible friction between the State Department and the National Security Council puzzle some viewers, U.S. officials will be on hand to answer questions.

In the first film, Morgan interviews five White House officials -- national security affairs adviser Zbigniew Brzezinski, press secretary Jody Powell, Office of Management and Budget Director Bert Lance, counsel Robert Lipshutz and presidential assistant Hamilton Jordan.

The audience even learns how to pronounce Jordan and gets a joke from him about having to take a taxi to work since Carter eliminated the limousine service of earlier administrations.

Brzezinski explains how a review of policy toward another nation would be conducted by the Carter administration. He also says the White House problem isn't getting information, it's having a perspective on it.

Asked about his thinking on White House press relations, Powell says it might be helpful if both sides in the press section remembered "the rather inconsequential nature of what we say and do on any given day."

He laments that neither officials nor the press is readily willing to admit error.

The second film is on relations between the White House and Congress and is built on interviews with Mondale, Byrd and House Speaker Thomas P. (Tip) O'Neill Jr. of Massachusetts.

The two congressional leaders speak cautiously of working well with the President, but insist that Congress has regained its strength after being weakened in the Johnson and Nixon years.

Shooting of the third film on the role of the Cabinet is under way and the fourth on Carter's foreign policy aims will not be completed until May.

Of the 110 USIA posts that have the equipment to screen the programs. 95 have already ordered the first one. The second recently began going out to overseas posts, according to USIA officials.
