Many have doubted this event's authenticity, however a team of four enterprising Auburn University students have decided to team up and make E.T.'s March, a documentary about them trying to locate the landfill where Atari buried all these games. Together, the four students will travel from Auburn, Alabama to El Paso, Texas, which is where the Atari plant was located. From there, they will travel from El Paso to the landfill in Alamogordo, recreating the path that the semitrucks took, while in the meantime taking in the video game culture of the United States.
Judging by the website, they seem very determined to locate this goldmine of video gaming history, and the documentary should prove to be a very interesting watch. Now, I haven't seen King of Kong, the other video game documentary that's been making waves lately, but I can imagine that E.T.'s March must have been inspired by it and the critical acclaim it has been receiving.
The filming of the documentary will take place from March 15-23 and will be released over the internet sometime this summer. There are no plans for a theatrical or DVD release stated on the website, but I assume that they would be willing to do something like that if the right distributor steps in and funds them.
While you're waiting for the film to be released, here's a great, well-researched site all about the E.T. burial story: http://atari.digital-madman.com/
