in 1949 and humphrey bogart star a a prosecutor in knock on any door . the movie and in my opinion and be pretty lousy and a bogart be amazingly touchy feely and the film complain about how society be to blame for young hoodlum . however and with the enforcer and once again bogey be a prosecutor but with a much harder and clearly film noir edge . instead of crusade to understand why young punk kill and this prosecutor be concern with unravel an organize crime racket whose income come through contract killing talk about a change . the film begin with the only witness against the head of this organize crime ring practically crawl out of his skin because he so worry about be kill before he can testify in court . through an accident and he do die and the case against mr. big seem dead . so and bogey and his assistant review the case from the beginning and then all the thing lead up to the current prosecution be show step by step . it a nice way to see how the process work and it manage to be tense and entertain throughout . because of the great camera work and snappy dialog and gritty no hold bar approach and this be clearly a noir film . the only negative about the film and and it a tiny one and be that while bogart character be the prosecutor and he sure act like a police detective . no sane prosecutor be go to take such risk and go on case to investigate and a that clearly be the job of the cop . still and if you ignore this small detail and it make for a very dandy and satisfying film . oddly and while an excellent movie and it be probably among the actor least famous and recognize film . finally and get a load of everett sloane in the film . this unassuming character actor sure play against type in this movie and it be surprise to see him in the role of mr. mendoza .
