A tale as old as time, reborn through Thai eyes and global screens – Onethong (Working Title) is Thailand’s next cinematic obsession. Onethong, a reimagining of the classic Thai epic poem, Khun Chang Khun Phaen, has just dropped its first teaser poster at the 78th Cannes Film Festival’s Marché du Film. As one of only five Thai projects selected to represent the country, Onethong made its international debut at the Producers Network Breakfast Meeting, the film drew attention from international distributors and cinephiles alike.
A film from Black Dragon Entertainment, Onethong follows its namesake heroine in a time when women must marry to secure their future. As she is caught in a love triangle between Khun Chang and Khun Phaen.
But this Onethong isn’t your traditional retelling. Inspired by the contemporary graphic novel Ratiros Mai Num Pa – a modern adaptation of Khun Chang Khun Phaen – the story follows Pimmada, a present-day woman who suddenly finds herself transported into the world of Onethong. Trapped in a love triangle that isn’t hers, she must navigate the fate of a woman caught between two men, fighting to survive and to rewrite her own ending.
The film is directed by Piyakarn Bootprasert and produced by Julian Jeong, whose past work includes Snowpiercer (2013), The Host (2006) and the Oscar-winning Parasite (2019). Onethong is also one of the films that received production funding from the Department of Cultural Promotion, Ministry of Culture and the Thailand Creative Content Agency (THACCA).
Get ready for one of the year’s biggest blockbusters as Onethong hits theatres in 2026.
