Trivia: By open admission of one of the original artwork designer Akira "Akiman" Yasuda, the movie (known in Japan as "The Street Fighter") inspired at least 2 of the most iconic backgrounds of the game Street Fighter 2: it is really obvious when you watch the fight between Jim Henry and "the kid", on the docks with a boat in the background much like in Ken 's stage. The cage fight against Henry inspired also Zangief's stage. (00:19:30 - 00:47:50)
