Mekhong Full Moon Party (Thai: 15 ค่ำ เดือน 11; RTGS: Sip Ha Kham Duean Sip Et; literally, "The 15th Day of the 11th Month") is a 2002 Thai comedy-drama about the Naga fireballs that arise from the Mekong at Nong Khai on the full moon in October. Written by Jira Maligool, the film was also Jira's directorial debut. The film takes a semi-documentary approach to its subject, examining the phenomenon and its accompanying festival, which draws thousands of people to Nong Khai each year, as well as providing a glimpse at Isan culture, Thai folklore and such practices as eating insects.
