The Weinstein Co. has bought world rights, excluding Asia and the U.K., to Ong bak 2, the sequel to 2003's Tony Jaa-starring Thai boxing hit Ong Bak: Muay Thai Warrior.

The deal was struck with sales arm Sahamongkolfilm Intl. on Friday, just after the wrap of Hong Kong's FilMart, and continues TWC's relationship with Jaa.

Ong bak 2 is in advanced development, with production skedded for the fall. Panna Rittikrai, scripter and action director of the original pic, is in negotiations to direct. Jaa takes an action director credit on the sequel.

Jaa plays a young man on a journey that teaches him the skills and inner meaning of martial arts.
