Portugal Colonial - Inside the fireproof vault housing US movie history

Which is why the US Library of Congress maintains a special, fireproof vault in Virginia, near Washington, DC.

There, the highly combustible nitrate film used from the dawn of cinema in the 1890s until the early 1950s has a permanent home, rarely accessed by the public but toured by AFP.

Lost movies on the volatile but durable medium are still being discovered and preserved in the facility. And thanks to digitization, the lost treasures can also be safely viewed for the first time in decades.

Some 145,000 film reels are stored in strictly fireproof conditions in a vast, chilly vault at the library’s National Audio-Visual Conservation Center in Culpeper, Virginia.

It is crammed with cinematic treasures that rekindle warm memories of an era when movies ruled.

The vault's leader, George Willeman, reeled off the names of classics with negatives there: "Casablanca," Frank Capra-directed films like "Mr. Smith Goes to Washington," and the grand-daddy of all action movies, "The Great Train Robbery" from 1903.

Down a spartan corridor so long it seemed to recede into the distance, he unlocked a series of cell-like steel doors.

Inside each of the 124 cells -- there's one dedicated just to the Disney archive -- were floor-to-ceiling cubby holes.

Each one held film canisters containing negatives and prints, all arranged meticulously: packed tight to prevent canisters from opening, but far enough apart to prevent any fire from spreading.

Since being set up in 2007 in a former US Federal Reserve building in the foothills of the Blue Ridge Mountains, the vault has maintained a perfect no-fire record.

- Film nerds' delight -

Nitrate film is just part of the center's collection of more than six million items of moving images and recorded sound. They also have supporting scripts, posters and photos.

Willeman, who sports a button badge with the invocation to "Experience Nitrate," said the Library of Congress began preserving the medium when in the 1960s, "it was discovered that so much film was being lost" due to fires and defunct companies throwing negatives away.

With the American Film Institute, the library began collecting and copying nitrate film, including the holdings of big Hollywood studios – RKO, Warner Brothers, Universal, Columbia and Walt Disney.

They also tapped the personal collections of film icons like movie impresario and silent era star Mary Pickford and motion pictures inventor Thomas Edison, whose early studio produced hundreds of films.

"We're 50 some years in, and it (the collection) just keeps growing," Willeman said.

With the arrival of digital media, the mission has expanded beyond preservation for purists and cinema historians -- who say movies just look better on nitrate footage -- to putting old films online.

"Now we can make them available for everybody, which to me, being the film nerd I've been since, like, third grade, is just amazing."

Nitrate film made by early artisans often preserves better than the later safety film, said Courtney Holschuh, nitrate archive technician.

At a workstation with no light bulbs or exposed batteries -- either of which could ignite dust or gas from vintage film -- Holschuh recounted how last September she carefully peeled apart a cache of 10 vintage reels donated by a retired schoolteacher.

There were 42 different titles on the reels -- only 26 of which have been identified. They included a lost film, "Gugusse and the Automaton," by French cinema pioneer Georges Melies.

"So much of our early film history is still out there for us to see and to experience," Willeman said.
