Here's more from the festival website:
When a homeless boy living at the youth shelter run by a Buddhist monastery turns up dead, the Abbot recruits Father Ananda, a former policeman, to find out why. He discovers that all is not well at this urban monastery in the heart of Bangkok. Together with his dogged assistant, an orphaned boy named Jak, Father Ananda uncovers a startling series of clues that eventually exposes the motivation behind the crime and leads him to the murderer. Based on the novel "Mindfulness And Murder" by Nick Wilgus.
Vithaya Pansringarm, hot at the moment thanks to his major role in Only God Forgives, stars as the serene sleuth in saffron.
Mindfulness and Murder screens on Thursday, September 12, at the Riverside Theatres in Western Sydney, with a Q-and-A afterward with Waller.
Waller is meanwhile gearing up to start casting for his next project, Chavoret: The Last Executioner, a biographical drama about the one-man firing squad of Thailand's death row. It will also star Vithaya, who will portray the marksman in his later years.
