Born in Thailand in 1961, Jira graduated in 1983 from Chulalongkorn University Faculty of Communication Arts, where he majored in film and photography. While still a student, he worked as a music video and movie commercial director.
In 1991, he co-founded his own film studio, Hub Ho Hin Bangkok (later working through the subsidiary Hub Ho Hin Films). In 2003, it partnered with GMM Grammy's film division GMM Pictures and Visute Poolvoralaks' company Tai Entertainment to form GMM Tai Hub (or GTH). In 2016, he became key person for GDH 559, a film studio that was the successor to GTH.
First features
Jira started out in feature films as the screenwriter for the 2000 film, The Iron Ladies (Satree lek), which was based on a true story about a gay and transvestite (katoey) men's volleyball team that won the Thailand national championship in 1996. The film went on to be a box-office hit in Thailand and has been a popular feature at international film festivals. It was directed by Youngyooth Thongkonthun, who's gone on to direct a sequel to Iron Ladies as well as another comedy, M.A.I.D. and 2006's Metrosexual.
Jira's second directorial effort, The Tin Mine, was a lavish production about a tin mine in southern Thailand in the 1950s. It was based on the short stories of Thai author Archin Panjabhan, who served as an adviser on the production. The film fared poorly at the Thai box office, but it has won several awards and has been featured at international film festivals.
