When a wild mechanic falls for an innocent girl, things can only go one way.
Written by Teruo Ishii and Isao Matsumoto, and directed by the former, Detonation! Violent Riders is an interesting mid-1970s take on motorcycle films, gang films, and crime films in general with a love story at its center. The story here is decently developed and has enough details to bring in viewers and make them want to stay. The violent is a touch gratuitous but not entirely out of place within the story’s frame. The characters are also decently written and given a bit to do here and there. However, anyone looking for a deep character study will leave empty-handed. This is not a study of the work it happens in, it is not a character study, it’s a film made to be entertaining period, and it does decent work at that.
The cast here is advertised as bringing Sonny Chiba back with director Teruo Ishii, but the one to watch here is really Kôichi Iwaki as Iwaki, the lead character, who gives a performance that brings you in and doesn’t let you go. He’s charming, he has charisma, and he makes the film what it is. His story is central, and he knows it. He also seems to know that he is up against Chiba and thus does his best to keep the attention on himself while giving a good performance. Playing his love interest Michiko, Tomoko Ai is charming, adorable, and soft spoken, playing the character sweetly and not making many waves. Junko Matsudaira steals a few scenes as Mayumi. She’s a fun one to watch. The cast works well together here, as enemies, friends, or lovers.
The film’s look works well for the story with solid cinematography by Yoshikazu Yamazawa. The images here show what they need to, add a little style and flare, and make the film so much more than the story at hand. This is how cinematography does its best, giving the film that extra touch without taking over unless it needs to.
Overall, this is a solid entry in the moto gangs sub-sub-genre with a decent story, good acting, and good imagery. It’s not groundbreaking but it works well, so it’s an easy watch.
In terms of this new release from 88 Films, the extras include some of the basics like the trailer and stills gallery, and some that are more interesting on this kind of release like the audio commentary and a new video essay. The presentation here is fantastic and looks great in high definition.
