In 2009, many in Iran believed the nation was on the verge of a new age of freedom and progress as young people were expected to play a key role in the upcoming presidential elections. Mir Hossein Mousavi, a long-time advocate of political reform in Iran, was expected to win handily, but to the surprise of most observers and the anger of many, the incumbent Mahmoud Ahmadinejad was declared the victor. The response was immediate and angry, and as Iranians took to the street to protest what many saw as a rigged election, Ahmadinejad's forces responded with violence, arrests and repressive tactics that were decried by human rights advocates around the world. However, if the revolt was unsuccessful, this time the Iranians were able to document the actions of the government and sent their message to the world through Twitter posts, internet postings and videos shot with amateur cameras and cell phones. Filmmaker Ali Samadi Ahadi used interviews, on-the-scene footage and animated re-enactments to tell the story of the Iranian revolution that failed and its legacy in the documentary The Green Wave, which was an official selection at the 2011 Sundance Film Festival.
