Serpico was released in 1973 and was one of two movies where Al Pacino, director Sidney Lumet, and producer Martin Bergman collaborated on (the other movie being Dog Day Afternoon). It was nominated for two Academy Awards including Best Actor for Al Pacino and Best Adapted Screenplay.
The film tells the true story of an undercover NYPD cop named Frank Serpico (played by Al Pacino) and his life through 1960 - 1972. He is an honest cop, who is excellent in his job, but lives in world of corruption and so he is assigned to catch those corrupt cops, even though it might cost him his social life.
The film does a great job at exploring the life of Serpico from where he was ecstatic about being a cop to when he had to live a life where he had to catch the corrupt, while trying not to get himself killed. He also had a difficult time in his social life where at first his relationships with his friends seems to go well, but his struggle with the police force has him distance himself from his personal friends, as well as his cop friends.
Al Pacino is magnificent as Frank Serpico, you identify the pain that he's going through with his intensity. In this clip, Serpico arrests a cop with anger in him and after he arrests him, he takes his frustration out by breaking a chair. After that, he goes to the chief of police saying that he's out, but the chief wants him to continue. What's great about both scenes is the ferocity Al Pacino brings in his character.
The film is excellent exploration into the corrupt world of New York, as well as the life of Frank Serpico, with gritty direction by Sidney Lumet, and a powerhouse performance by Al Pacino.
