Alex Gibney, the famed documentarian behind the the jaw-dropping film Going Clear that investigated the Church of Scientology, has a new movie that explores Stuxnet, a piece of Malware created by the United States and Israel to take down Iranian nuclear facilities. The director just sent Gizmodo his latest trailer.

Stuxnet is considered to be one of the first pieces of malware created by one nation to attack another nation. And it worked. After Stuxnet was deployed, it eventually infected an Iranian nuclear centrifuge and slowly destroyed it. The facility operators had no clue.
