While it was able to survive the rigors of traversing the space time continuum, lightning strikes and a retaliation attack by Libyan terrorists, there was one destructive force the DeLorean from "Back to the Future" couldn't outrace: time itself. 

Of the five original DMC-12 DeLoreans used in the filming of the "Back to the Future" trilogy, the original “A” Hero DeLorean time machine (the one used in all three films for close-up shots) was left out to rust on a Universal Studios Hollywood lot. In 2010, the 25th anniversary of the first film's release, Universal decided to partner with "BTTF" co-writer and producer Bob Gale, as well as a dedicated team of fans and car enthusiasts, to fully restore the "A" Hero DeLorean in all its glory. The more than five-year rebuild is now the focus of a new documentary titled "Out of Time: Saving the DeLorean Time Machine."

"It had been sitting out in the rain for years," film historian Rob Klein says in a Kickstarter video for the film. "And all of these pieces started to fall off the car."

Added Alex Abdalla from the restoration team: "Every animal possible made a home inside the car."

Gale says that fans in particular were rough on the vehicle, using the open access to steal some personal mementos. "The flux capacitor and the time circuits were missing," says Ara Kourchians. "The most essential parts of the time machine were just gone."

For "Out of Time," producer Steve Concotelli documented the entire restoration process for over a year - capturing all the "amazing discoveries to frustrating setbacks." The original $25,000 goal was shattered in less than two days, and currently stands at $60,000. 

"Every extra dollar is vital to increasing the quality of the film," the team writes. "More interviews, more licensed clips, an awesome music score - all which will make this a greater movie experience for everyone!"

Check out a trailer for the film below. Should all go well, "Out of Time" will be released in October.
