Filmmaker Annie Goldson discusses her latest film premiering at the New Zealand Film Festival "Brother Number One"

"The notorious head of the Khmer Rouge regime (1975-1979) in Cambodia Pol Pot called himself Brother Number One. Kerry Hamill, a Kiwi sailor who ran a charter yacht business out of Darwin was also "brother number one" the oldest in the Whakatane Hamill clan. In 1978, advertently, Kerry and his friends took shelter in Kampuchean waters during a storm, were picked up, tortured and murdered by Pol Pot's men. Rob Hamill, Kerry's younger brother and an Olympian sportsperson, returned to Cambodia this year in 2009 and 2010 to face the perpetrators at the ECCC, the Extraordinary Court of Cambodia, a war crimes tribunal."
