“Letters To The President” is a documentary about Iran’s controversial President Mahmud Ahmadinejad. Czech-Canadian filmmaker Peter Lom was allowed to film Ahmadinejad on his travels in the Iranian provinces, where he would meet with crowds of people, many of whom had sent him letters about their daily needs. The 72-minute film was recently screened at the Berlin International Film Festival, also known as the Berlinale. In an interview with RFE/RL’s Golnaz Esfandiari, Lom, the only Western journalist taken on Ahmadinejad’s provincial trips, said his access to the president was limited — but was enough to gain an inside look at his peculiar brand of populism.
