D: Jean-Stéphane Sauvaire (Johnny Mad Dog).
S: Joe Cole, Vithaya Pansringarm, Nicolas Shake, Pornchanok Mabklang, Panya Yimmumphai.
If not based on a true story, you would think A PRAYER BEFORE DAWN was a B-movie story with A-movie craft. A Brit survives a Thai jail by fighting in the inter-prison martial arts tournaments. A brutal, minimalist biopic.
