Tong Po (Michel Qissi) hurt himself throwing Gene LaBell out of the ring causing the local fire department to roll to the set, even though Michel was fine within an hour without the medical attention.
The arena in which the major fights take place is the Bren Events Center of the University of California, Irvine. Many of the spectators are UC Irvine students.
David and his manager talk about taking some exhibition kick-boxing bouts like Kurt used to take. This is impossible, because Kurt Sloane never competed in kick-boxing in US. Even though he did have previous martial arts experience, his background was in karate, not kick-boxing. He only had two kick-boxing matches before he was gunned down by Tong Po, and both of them were in Thailand.
When David delivers the final kick to Sanga, he raises his left leg to kick but in the next frame it is clearly his right leg which comes out and makes contact to Sanga's face. The right-leg is also a prop made of rubber as you can see the crews hand holding onto the thigh part and the rubber foot flopping/wobbling when contact is made. The following frame shows David bringing back his left leg after the right-legged kick.
When David delivers repeated kicks to Sanga (Tong-Po's manager), Sanga's face is covered in blood during the face-kick, but the blood has disappeared in the next frame during the groin kick, and then re-appears during the next kick.
Ring Announcer: We apologize for the delay. But there has been a change. Lightning Lou Lescano has withdrawn from the fight. Fighting in his place, from Thailand, the fighter name is Tong Po, ladies and gentlemen. Tong Po!
