It seems that Mr. Miyagi didn’t have the materials or finances to make or sponsor a black belt for LaRusso. In the registration scene where the official is explaining that only brown belts and above are allowed to enter, Mr. Miyagi spots a black belt in a gym bag and sneakily pilfers it under the guise of correcting the spelling of his name to the registrar.
While asking the registrar to change his name from ”Miyaji” to “Miyagi”, he sneakily hands the belt to Ali Mills.
The Secret Karateka Crew Member
Ron Thomas, who played the part of the Cobra Kai thug Bobby Brown was one of the only four people on the set who were trained in martial arts. Thomas was so well trained in fact that he brought with him a black belt in Ju-Jitsu.
His experience in martial arts allowed convinced director John Avildsen to allow Thomas to choreograph all his own fight sequences.
Mr. Miyagi Beats a Samurai
Toshiro Mifune was the sort of actor that one automatically would assume would be ideally suited to play the character of Mr. Miyagi. A native of Japan, Mifune was renowned for starring in numerous samurai films.
Now, whereas producer Jerry Weintraub was reluctant to cast Pat Morita for his comedic background, director John Avildsen found Mifune “too serious”. His naturally imposing demeanor didn’t translate well into the character of the much kinder Miyagi.
The Fastest Black Belt in History
Either Daniel LaRusso is a prodigy beyond all prodigies or there is a time warp in 'The Karate Kid' universe. Let’s just stick with linear time here. Mr. Miyagi begins his training of LaRusso on the first of November.
The All Valley Karate tournament is less than fifty days away from his start of training yet by the time the tournament rolls around, LaRusso is a fully qualified black belt. Take into consideration that black belts are usually achieved after 5 years of weekly training!
The Karate Copyright
While DC Comics obligingly allowed Columba Pictures to use 'The Karate Kid' name, a karate teacher from Brooklyn took umbrage at what he perceived to be a clear copyright infringement. Bill DeClemente sued Columba Pictures and Jerry Weintraub.
DeClemente’s case was dismissed though as the courts found that his claim of being known as “The Karate Kid” was not wide enough so as to damage his business dealings in any way.
