Watch part two In depth The latest on Iran's post-election unrest Who's who in Iran Send us your videos and pictures from Iran Following the results of a disputed presidential election Iranians poured onto the streets in their tens of thousands to protest the re-election of incumbent Mahmoud Ahmadinejad.
The demonstrations were unprecedented both in their scale and nature and the largest of their kind since the Islamic revolution in 1979.
The figurehead of the protesters, defeated presidential candidate Mir Hossein Mousavi, has not been seen in public since the demonstrations began and the authorities violently repressed opposition protests.
Although Iran's supreme leader, Ayatollah Ali Khamenei, has declared there will be no re-run of the elections and dozens of opposition so-called reformists have been detained, Mousavi has urged his supporters to maintain their protests through peaceful means.
In a special documentary Al Jazeera charts the political trajectory of Mir Hossein Mousavi. A former prime minister, now billed as a leading reformist, we discover his more hardline roots, and ask whether he is really the desired leader of the reform-hungry masses or merely an accidental hero in the right place at the right time as frustrations of Iranians from diverse camps reach boiling point.
Mousavi and the Masses can be seen from Friday July 3 at the following times GMT: Friday 1630; Saturday 0300 and 1130; Sunday 0530; Monday 0830 and 2330.
