Cobra Kai

During the original Karate Kid shoot, late director John G. Avildsen shot hours of tournament footage from multiple angles. The crew behind Cobra Kai searched the studio vault and found a ton of never-before-seen clips, which they were able to introduce into the series via flashbacks. One of them includes Zabka's real life mom, who was in the stands in different angles that went unseen until 2018. Ralph Macchio told Uproxx there are three brand new angles of the famous crane kick.

Many people believe that Miyagi's name on his headstone is a continuity error, given that in The Next Karate Kid (1994) his name is stated to be Keisuke, but it was actually shown previously on a sign being held for him by Chozen in The Karate Kid Part II (1986) to be Nariyoshi. This means that it was The Next Karate Kid that changed his name, while Cobra Kai kept the name previously given for him.

Another interesting fact, however, is that the name given in The Karate Kid Part II was not the original first name given to Miyagi. In The Karate Kid (1984), it can briefly be seen on Miyagi's dog tags, attached to the keys of the 1948 Ford given to Daniel for his birthday, that Miyagi's first name is Hideo.
