The Street Fighter is a Japanese martial arts film released in 1974 and produced by Toei Company Ltd. It was released in the US by New Line Cinema and became one of the first films to be a commercial success for the distributor. It is notable as the first film to receive an X-rating in the United States solely for violence. In the UK it was originally released as Kung Fu Streetfighter, presumably to avoid confusion with the Charles Bronson movie Hard Times which was initially released as The Streetfighter in the UK.
The Street Fighter inspired two sequels, Return of the Street Fighter and The Street Fighter's Last Revenge. Additionally, the film Sister Street Fighter and its sequels is a spin-off series of The Street Fighter. There was another spin-off entitled Kozure Satsujin Ken, which was brought to the US by a different company under the title Karate Warriors. The film is in the public domain.
In 1993, the film (and its sequels) received mainstream exposure in North America when they were featured in Tony Scott's True Romance (written by Quentin Tarantino), which had the two lead characters spending time at a Sonny Chiba Street Fighter marathon. Quentin Tarantino listed The Street Fighter as number 13 on his top 20 grindhouse films list. Sonny Chiba was also cast as Hattori Hanzo in the film Kill Bill.
