The dojo "Bruce" takes a lesson in is the same dojo that appeared in 'The Karate Kid' franchise which was soon around the corner about a couple of years later.
The movie was a box-office success in the USA despite launching in only 325 theaters.
The 25th-Anniversary Edition DVD of this film was actually released 27 years after the film's theater debut.
The movie spurred just one sequel which was made and released around five years later; They Still Call Me Bruce (1987) was not successful commercially and went straight to video in a number of territories.
