This is one of Deodato's earlier films. Deodato is best known as the director of the notorious film "Cannibal Holocaust". With a script by Di Leo and masterful direction by Deodato, you get a film that is violent, ruthless and exciting. One can easily see the influence on contemporary directors like Tarantino (a huge Di Leo fan). This film also has a lot in common with movies like Dirty Harry, where a cop uses extreme measures to deliver justice and always has his boss coming down on him for being too violent in doing so. Except in this film it is two guys who team up to clean the streets. The viewer will be surprised at the amount of violence in this film when considering the year it was made. If you can locate this film, its worth watching.
