"Born in the Surin Province of the Isan region of Thailand, Jaa grew up in a rural area and watched films by Bruce Lee, Jackie Chan and Jet Li at temple fairs. While doing chores or playing with friends, he would imitate the martial arts moves he had seen in the films. He would practice in his father's rice paddy or, when bathing the family's elephants, he would somersault off their backs into the river.
"What they did was so beautiful, so heroic. I wanted to do it, too," Jaa told Time in a 2004 interview. "I practiced until I could do the move exactly as I had seen the masters do it."
At age 15, he looked up Panna Rittikrai, begging the veteran Thai stuntman and action-film director to take him on as a protege. Panna instructed Jaa to attend Maha Sarakham College of Physical Education in Maha Sarakham Province. The most early films was "Hi Chad" it was an old thai movie produced by Jaa when he was 17. The movie was about a little boy searching for life."
