Prince Chatrichalerm's parents, Prince Anusorn Mongkolkarn and Mom Ubol Yukol Na Ayudhya were filmmakers and co-founders of the Lavo Pappayon Company. His uncle was Prince Bhanu Yukol, a pioneering Thai filmmaker. Chatrichalerm was sent to Australia for schooling, and from there he went to UCLA, where he graduated with a degree in geology. His minor was film studies, and he shared classes with Francis Ford Coppola and Roman Polanski. He also worked as an assistant to director and producer Merian C. Cooper.
Early films
Though he's best known for his work on Suriyothai, Chatrichalerm's filmography stretches back to the 1970s. His first film, 1971's Out of the Darkness, was the first Thai science fiction film. He was among the first of a new wave of Thai directors to produce films reflecting changes in society. One of these films was his Khao Chue Karn, based on a well-known story by Suwannee Sukhontha. Released in the months leading up to the bloody pro-democracy student uprisings of 1973, Dr. Karn dared to address corruption in Thai society. Even Chatrichalerm's status as a prince didn't rate when the authoritarian government's censor wanted to cut the film. Chatrichalerm personally showed the film to Field Marshal Thanom Kittikachorn and was able to persuade the dictator to let the film be released uncut.
Social message films
Most of Chatrichalerm's films have some kind of social message, such as the downside of prostitution, teenage sex and delinquency, protecting the environment, or the evils of the drug trade. His films resist depicting any glamor, focusing on the poor, downtrodden working classes, such as Freedom of Taxi Driver or Song for Chao Phya and often with gritty action, such as Gunman, Salween, and The Colonel. Three of his films from this period were submitted by Thailand for the Academy Award for Best Foreign Language Film: The Elephant Keeper, Song for Chao Phya and Daughter 2.
Royal epics
Around 1999, Chatrichalerm embarked on the most ambitious film project of his career, The Legend of Suriyothai, a lavish production about a 16th-century Siamese queen, Suriyothai. For his production, he received the backing of Queen Sirikit and the royal family. The film was at first conceived as being eight hours long. By the time it premiered in Thai cinemas, it was nearly three hours long. An even-more-condensed version was released in the United States in 2003, edited and "presented by" Francis Ford Coppola, a former classmate of Chatrichalerm's from UCLA. After Suriyothai, Chatrichalerm started work on an even bigger project, King Naresuan, about the 16th century Siamese monarch, Naresuan. More epic in scope than Suriyothai, Naresuan was initially released in two parts in early 2007. Under the title King of Fire, the second part of the series was submitted by Thailand for the Academy Award for Best Foreign Language Film. As of late 2007, a third part is scheduled to start production in early 2008.
Bankruptcy
On June 5, 2012, Chatrichalerm was adjudged bankrupt by the Central Bankruptcy Court and was placed under an absolute receivership, causing his ongoing King Naresuan project to be halted.
