Ong Bak 3!
Watch the trailer here.
Although his movies (filmed in Thai) are uneven, Tony Jaa is an incredible martial artist who delivers bone-crunching raw Muay Thai power.
The first Ong Bak is one of my favorite martial arts movies.
In fact, Tony Jaa performs aspects of the Thai art that are older than the sport of Muay Thai. For example there is a lot of spear action in the upcoming movie.
