The Watergate tapes of Richard Nixon's presidency weren't just audio.

The FBI also confiscated 204 reels of Super 8 home movies shot by three Nixon aides who played roles in the Watergate scandal -- footage now featured in a forthcoming documentary about that extraordinary presidency.

Our Nixon "is a feature-length documentary presenting those home movies for the first time, using them to create an intimate and complex portrait of the Nixon presidency from its idealistic beginning to its tragic end," says promotional material.

YouTube has a trailer for the film, including a bouncy campaign theme song (Nixon Now! More Than Ever!).

The film will be shown Sunday at a film festival in New York City.

The Super 8 movies were filmed by Nixon aides (and Watergate conspirators): White House chief of staff H.R. "Bob" Haldeman, chief domestic adviser John Ehrlichman and special assistant to the president Dwight Chapin.

Say the promoters:

"Haldeman, Ehrlichman and Chapin filmed dozens of hours of footage from 1969 to 1972, capturing the prosaic and the profound. They filmed big events like the Apollo moon landing, huge anti-war demonstrations, the Republican National Convention, Tricia Nixon's White House wedding and Nixon's world-changing trips to China and Russia.

"But they also filmed everyday life (albeit everyday life in some pretty unique circumstances): Ehrlichman eating dinner off a tray on Air Force One, Chapin mugging for the camera during a staff meeting, the contents of Haldeman's White House desk. Ehrlichman was quite fond of filming hummingbirds.

"These three men carefully documented their time with Nixon because they believed that Nixon would transform America. And in a way, they were right."
