Watch: The Last Executioner teaser

No one forgives The Last Executioner for his sins. Not the prisoners he's had to kill, not his wife, and nor "the spirit" that haunts him.

So feast your eyes on the teaser trailer (embedded above) to The Last Executioner (เพชฌฆาต, Petchakat), director Tom Waller's new feature. It's a fact-based biographical yarn about Chavoret Jaruboon, a rifleman who was the last to carry out executions in Thailand's prison system.

He was carefree rock 'n' roller with one foot in his grave, playing music for American soldiers fighting in Vietnam before he stumbled on his lethal vocation. He served for 19 years as Bang Kwang prison's last machine-gun prison executioner.

Vithaya Pansringarm (Chang from Only God Forgives) stars as Chavoret with Penpak Sirikul (She, It Gets Better) as his wife. David Asavanond (Countdown) is "The Spirit", a character who haunts him throughout his life. Thira Chutikul (Rang: The Parallel) plays Chavoret in his younger days. They are supported by veteran character actors Nirut Sirichanya (The Hangover Part 2, Ong-Bak 2 and 3), Jaran Petcharoen (Mindfulness and Murder) and Pisarn Akraseranee.

The film is still in production and will be released in June through a new Thai outfit, Handmade Distribution, which has previously brought Lee Daniels' The Butler and Don Jon to Thai cinemas, and has Chinese fantasy epic The Monkey King coming out this week.
