Contacto sangriento

Jean-Claude Van Damme actually knocked out Bernard Mariano with his elbow. The scene made it into the movie.

When Lin is escorting Frank and Ray to the "Narrow Corridors" before entering the Kumite for the first time, he greets the older Asian man who famously says "OK USA!" At that time, Lin has a scruffy beard. When they get to the Kumite to meet the judges, he is clean shaven. Later on in that scene, his beard returns.

Before the credits the following can be found: This motion picture is based upon true events in the life of Frank W. Dux. From 1975 to 1980 Frank W. Dux fought 329 matches. He retired undefeated as the World Heavy Weight Full Contact Kumite Champion. Mr. Dux still holds four world records: Fastest Knockout - 3.2 seconds Fastest Punch with a Knockout - .42 seconds Fastest Kick with a Knockout - 72 mph Most Consecutive Knockouts in a Single Tournament - 56 Subsequently Mr. Dux founded the first American Ninjitsu System. Dux-Ryu.

Finnish version is censored (over 20 minutes). The cuts include almost every fight of the movie, Jackson's first fight is heavily cut, every Chong Li's fight is cut to pieces. The whole sequence where the "Kumite"-song is heard and it shows several fights is removed, and the final conflict between Dux (J-C Van Damme) and Chong Li (excellent Bolo Yeung) is extremely cut (several minutes).
